JButton won't show another jframe

I'm currently working on a project and whenever I click the jbutton on jframe 2 (the 2nd jframe after the log in) "set appointments"/btn1, it won't show the other jframe which is jframe3.
The program itself works but the button won't show the other jframe.

I'm a beginner in java and I really want to know how to fix this problem.

You're shooting your own self in the foot with:
if (btn1.isSelected()){
// ...
}
There is no need for this block of code -- a button isn't "selected" unless it extends from JToggleButton (such as JCheckBox) and has been checked, something that a JButton does not allow, and what is more, it is preventing the listener's code that it holds from running. Solution: just get rid of it.

Java Text Field Not Updating

I am trying to make a calculator program where click a button and then it would add to the Java Text Field(Not the Java Text Area), and I use the ActionEvent e to figure out the action. Then using the actionCommand where I get the actionListener I try to add the text to the java text field. And somehow it is not updating into the java text field. Is this a problem with repaint or something.
Here's my code

You have two different JTextField variables that are both named jtf.
The first is an instance variable, which you have declared with JTextField jtf = new JTextField();, and is accessible from anywhere in the class.
The second is a local variable, which you have declared with JTextField jtf = new JTextField("This is the text field");, and is only accessible in the constructor of Calculator.
The problem is that the second jtf (the local variable) is being added to the UI, while the first jtf (the instance variable) is what's being updated by the action event.
To fix this, change this (near the top of the class): JTextField jtf = new JTextField();
to this: JTextField jtf;
And then change this (in the constructor):
JTextField jtf = new JTextField("This is the text field");
to this: jtf = new JTextField("This is the text field");
Then, you'll only have one jtf variable (which will be an instance variable), and your action event should work.

Just remove this line:
JTextField jtf = new JTextField("This is the text field");
from constructor.
The first is an instance variable, JTextField e.g. jtf is accessible from anywhere in the class.

How to clear JFrame when JButton is clicked to call/display the other JFrame?

I have this code. When I run it, it displays a JFrame "menu" with two choices. When I click on a button it now displays the menu AND the new JFrame in the same window. And when I click on the other button, it adds with the existing things displayed on the same Window and adds and add inside. I'm thinking of using just one window/JFrame. How do I clear out the past JFrame? Is this possible?

For titles on JPanel, you can use Title Border as below.
TitledBorder title = BorderFactory.createTitledBorder("YOUR_TITLE");
YOURPANEL.setBorder(title);

You could try creating a border above each of the panels like this example:
Make a JPanel border with title like in Firefox

Try this:
myPanel.setBorder(BorderFactory.createTitledBorder("MyTitle"));

I think you want to set the title on the frame and not the panel. JPanels don't have titles, but their parent frames do.
Try this:
SwingUtilities.getRoot(yourPanel).setTitle("SomeTitle");

Adding a TextField to a program

I am making a better version of an application that was given to me. I still need to have the same components as the program that was given to me, I just need to reorganize it. I was also told not to copy any of the original code and do it from scratch. The first screenshot shows the textfield I need to add to my program from the original program. The second screenshot is my program. I am not sure if a JTextField would be best for this. My code is below. I have tried to add a JTextField with a JLabel and center it but when I run the program it covers everything else in the program and only shows a little white box.
