Why doesn't a panel with GridBagLayout show the content?

I wrote a little something here. It's working if I don't backPanel.setLayout(new GridBagLayout);
But without the grid bag, the content stays in the top left I maximise the screen.
With the grid bag I only get the red backPanel in the frame. Well, there is a gray pixel in the middle of the screen. I'm assuming that's my panel, but I can't make it bigger. I tried setSize but it doesn't change. Also, I had the panel.setBounds(0, 0, getWidth(),getHeight());. I'm not sure why I removed it.
My main is in the other file. The only thing it does at the moment is to call the LoginFrame.
Here is the code:

backPanel.setBackground(Color.RED);

panel.setSize(500, 300);

panel.setLayout(null);

panel.add(label = new JLabel("Username:"));
label.setBounds(20, 100, 100, 25);

panel.add(button = new JButton("Register"));
button.setBounds(240, 200, 100, 25);
button.addActionListener(this);
button = defaultActionKeyEnter(button, KeyEvent.VK_ENTER);
//add(panel);
backPanel.add(panel);
add(backPanel, BorderLayout.CENTER);
revalidate();
repaint();
setLocationRelativeTo(null);
setVisible(true);
}
public static JButton defaultActionKeyEnter(JButton button, int desiredKeyCode) {
InputMap inputMap = button.getInputMap(JComponent.WHEN_FOCUSED);
KeyStroke spaceKeyPressed = KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0, false);
KeyStroke spaceKeyReleased = KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0, true);
KeyStroke desiredKeyPressed = KeyStroke.getKeyStroke(desiredKeyCode, 0, false);
KeyStroke desiredKeyReleased = KeyStroke.getKeyStroke(desiredKeyCode, 0, true);
inputMap.put(desiredKeyPressed, inputMap.get(spaceKeyPressed));
inputMap.put(desiredKeyReleased, inputMap.get(spaceKeyReleased));
inputMap.put(spaceKeyPressed, "none");
inputMap.put(spaceKeyReleased, "none");
return button;
}
// Unfinished code dont worry bout it...
#Override
public void actionPerformed(ActionEvent e) {
if (e.getActionCommand().equals("Login")) {
if (textField.getText().equals("Heinz")
&& (new String(passwordField.getPassword()).equals("password123"))) {
// color = Color.GREEN;
} else {
JOptionPane.showMessageDialog(this, "Wrong Username or Password", "Error", JOptionPane.WARNING_MESSAGE);
// color = Color.RED;
}
} else {
JOptionPane.showMessageDialog(this, "Cya");
dispose();
setVisible(false);
}
// panel.setBackground(color);
}
}
I have seen questions about this but none of the answers were helpful in my case.
Calling the following didn't help.
revalidate();
repaint();
Did I maybe add it in the wrong order?
And how does the code look like to you? Would you consider this clean?

The layout of backPanel will mis-calculate the dimensions of "panel" because "panel" does not participate in layout management properly, without a layout manager of its own.
One solution to this is to use setLayout(null) also on the "backPanel", or add "panel" directly to the JFrame.
With the first suggestion ("backPanel.setLayout(null);" just after it is created), plus the following main method:
public static void main(String[] args) {
new LoginFrame();
}
I get this:

JPanel gets compressed and disappears when trying to move to the bottom

I have to do a project in Java and thought a GUI Text Adventure would be cool. My Problem is that when I create a JPanel and move it further down on the screen, the panel first changes its size and then disappears completely at one point.
On the GameScreen there should be a panel for choice Options to be put on but it refuses to go further down than about half the size of the Screen.
Here's the code:

Here is a basic implementation using layout mangers, avoiding the bad practice of null layout manager.
It is not an optimal one, but should get you started:

how should i navigate from one window that uses an application window to another frame in another application window?

i am developing an application for which i have created different application windows. Now i'm in a confusion on how i can link one to another using a button, that is when i click a button, it has to navigate to the other application window. I have tried it with frames from same file, but that doesnt satisfy my need.

Why isn't anything showing up in my JFrame?

Why is my GUI not showing any buttons, labels, or text fields?
I think I have it all setup, but when I run it, only the frame shows, and none of the contents appear.

Move your setVisible() to the end of the constructor. You are adding all of your components after you set your JFrame up and make is visible, so you don't see any of the changes.
This should show your JFrame with all the components:
public Gui(){
setTitle("Basic Gui");
setResizable(false);
setSize(500, 200);
setDefaultCloseOperation(EXIT_ON_CLOSE);
Container pane = getContentPane();
pane.setLayout(null);
button = new JButton("button");
button.setBounds(50, 60, 50, 70);
bHandler = new buttonHandler();
button.addActionListener(bHandler);
label = new JLabel("Hello", SwingConstants.RIGHT);
label.setBounds(50, 60, 50, 70);
textField = new JTextField(10);
textField.setBounds(50, 60, 50, 70);
pane.add(button);
pane.add(label);
pane.add(textField);
setVisible(true); // Move it to here
}
Here's what the frame's looked like before and after I moved the setVisible statement and compiled your code.

selectie.setBounds(60, 500, 99, 25);
selectie.setActionCommand("selectie");
label.add(selectie);
pack();
addHomeListener(new HomeController());
}
}
Code from the button:
package Controller;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import View.Home;
import View.Selectie;
public class HomeController implements ActionListener {
public void actionPerformed (ActionEvent e){
Selectie selectie = new Selectie();
selectie.setVisible(true);
}
}

Please do give valid attention to what #kleopatra and #mKorbel, has to say, they are very much right in pointing that out to you to make things easier.

I'd suggest to use CardLayout, most easiest, very confortable for (+1 for SSCCE) your code posted here
never create, re_create bunch of another JFrames, only in the cases that you have got very important reasons, then use JDialog with parent to the JFrame
