How to show GUI design view in java.class?

I'm linking a database to NetBeans now and I need to create a interface for this. But when I need to adjust the position of button, label is difficult. Is it possible that show a GUI design view that easy for me to adjust without use the JFrame component?

If I understood your question correctly, you're looking for a GUI builder for Swing.
Netbeans ships with the Matisse Swing GUI Builder which will help you build GUIs easily and quickly. Tutorials aren't uncommon (such as the official tutorial or some user created videos on YouTube).
Some folks are fine with this work flow (since it speeds up development quite a bit). Others want to use custom frameworks and have requirements to use specific layouts in which case I recommend reading about different layout managers.
Take your pick and happy development! :)

Instead of trying to design your entire application in the GUI editor, you may be able to adapt the approach shown here. This will let you focus on a single container at a time. Also, remember to backup your .form files; more here.

Using Swing GUI for NetBeans to Set Background of a JFrame from a Resource

My friend and I are working together to write a Java program, and I am taking on the task of designing the GUI. Our GUI requires a background image for the JFrame, and the image needs to be able to change based on the user's actions. I have placed the images that I want to use as the background in the project as a resource, and I would like to ask for help finding the resource path, and setting the resource path as the background image in the JFrame.
I am using the Swing GUI Builder for NetBeans to design the GUI. Can someone please offer me some help? I have no experience with GUIs, and my friend has little experience with basic Java coding, so we are assigning parts based on our knowledge.

If you don't want to resize the images (as the frame changes), you could simply set the frames layout to BorderLayout and use a JLabel to display the images. Otherwise you will need to construct a custom component (using something like JPanel) and render the image yourself
Looking up embedded resources is a simple process of using something like getClass().getResource(...), where the parameter is the path to the resource, where the root is the top level source folder in your project.

How to make overlay for video in swing

I want to make a transparent overlay for a foreign project to show live video. Sample of overlay is given in the image link below. In image you can see a overlay at right bottom corner showing face of a person, I also want to achieve same functionality using JMF to show face and then display the face in overlay using swing.
Sample Overley Imahe: http://www.ovostudios.com/images/vidsamsolo.jpg
Can someone help achieving this functionality?

If you're just starting the project and haven't actually got the JMF part up and running yet, then you might want to take a look at some alternatives before committing to it.
If you want to go ahead with Swing, to get the general overlay behaviour you want, you'll need to make use of Frame.setUndecorated() to turn off window borders and buttons, and Window.setAlwaysOnTop() to make sure the window stays on top of other windows. For the transparency, see this tutorial. However, I'm not sure whether transparency and video will work nicely together, so good luck!
You might also want to write a custom focus handler for the window so that it cannot be focused, although it is probably impossible for the overlay to be properly 'phantom' whereby clicks just pass through the overlay to the underlying desktop. That kind of behaviour might only be possible by using low-level graphics techniques i.e. by not creating a window at all, but by drawing directly onto the screen. That might require a native library.

Turn photoshop design into Java GUI

I can't seem to find anybody who has done or posted something like this; Essentially I want to design my own UI in photoshop and then slice down the images to use it in a Java application. Essentially coding in the PSD file as the GUI. Is this possible? If so, can anybody lead me in the right direction?
I'm not sure what editor to use for this sort of stuff. I am using the Eclipse IDE and I know there is a Visual Editor but, I already have the actual design for every component in a PSD file. All I want to do is to start incorporating this into the application. Thanks.

It depends on how far your design goes. If you simply want to have normal Swing components on top of your image this is easy. Convert your PSD into (for example) PNG, create a custom JPanel subclass that loads the image and overwrite the paintComponent() method to draw the image instead of the normal background. All child components can then be set to be transparent with setOpaque(false). This puts your image into the background and puts the components float on top of it.
If you want to change how individual components look, its a lot more work. You basically need to implement a new Look&Feel for Swing. I wouldn't recommend going that route, unless you really have to, we are talking about weeks of work here, and it requires a lot of testing to really make it work properly on all platforms.
Alternately, there are already tons of custom Look&Feels available, I suggest you take a look at some freely available ones (just google "java look and feel"). Many of them can be customized to some degree (how much depends on the actual implementation, so take a close look at the source/documentation for each of them).

You might want to take a look at NetBeans which has a Swing GUI Builder. You would have to redraw your components there, and then write all the code to process the events. It is sometimes good to start with that, though often times it is less frustrating to lay them out with code by hand as it can difficult to make changes in code and have the builder keep up. There is nothing I know that will let you start from a photoshop image and proceed to building a GUI. Sounds like a good project to make someone rich. :-)

java swing app with a custom titlebar?

Is there a way to write a Java Swing application with a custom chrome? Please take a look* at the frame for Microsoft's Zune 4.0 software.
I realize that colors, the shape of scroll bars, etc. are controlled by skins or looks and feels. Right now I'm trying to tackle the native window which houses the java components--the title bar mainly.
Thanks

By default the frame of a JFrame is native. This can be removed by calling Frame.setUndecorated. The Sun Window PL&F does not provide a title bar. You could hack aJInternalFrame so that it draws the frame, although that probably isn't going to be as easy as it may seem. Of course, if you are going the full custom route, you can draw whatever you want. From 6u10, Sun's JRE also provides APIs to make windows transparent and non-rectangular.

No part of a Swing component's look and feel is "native" in any way. Swing components are "lightweight", which means they are entirely drawn on the Java side, and not at all on the windowing system side.
To create custom "chrome" you create the UI delegates for one or more components. In yor case, you'd want to muck around with the delegates for JRootPane and JInternalFrame.

The Look and Feel of Swing apps are pluggable..that is it can change on the fly. You can create your own look and feel but its not a simple undertaking. To get started this tutorial explains. This article does a little more.
This project demonstrates what could be done. So its up to your imagination.
