need help on java GUI
Question
I'm creating a three card poker game on Java. I'm basically done with coding now, but I meet some problems with GUI stuff. Here's my code for the graphics part:

}
The major problem is that in createAndShowGUI() , if I put that while loop, which I tried (for loop, do loop) there, the JPanel will just show up but nothing in there. If there is no while loop in there, the JPanel will show up regularly with all the stuff on there. But I need the the code inside the while loop, for the code there is basically the game.
I tried to make a method of its own( play() ), but if I call it in main() , or anywhere, the JPanel will be white(nothing).
Here's my 2nd question: If you delete the while loop and the JPanel shows up normally, you'll see the computer's hand and player's hand, but in text form. I want to know how to substitute the text with images.

There are few things, not all of them are directly GUI related:
Lose static members , they should not be there, I assume you used them since everything is called from the main method, but this is not the way to go. Java is an object oriented programming language, create classes, instantiate them and use them, don't perform all the work in one class, which is not even instantiated.
Refactor repeating code , instead of creating different classes with the difference of one value, create more generic classes. For example, instead of 5 different classes like that:
static class ten implements ActionListener{
public void actionPerformed(ActionEvent e){
if(playermoney<10)
wlt=9;
else
bet=10;
}
}
Declare one class like this:
static class ten implements ActionListener{
int money;
public ten(int money) {
this.money = money
}
public void actionPerformed(ActionEvent e){
if(playermoney<money)
wlt=9;
else
bet=money;
}
}
and instantiate it with the appropriate int according to the case.
Let the application be event driven . Since the player has to interact, don't use a big while loop, instead trigger the events (eg what case happened now) from the listeners (ie user pressed a button)
Related to the previous point, don't perform long actions (like your entire program) on the UI thread, it will not let the UI be updated, perform all the work on a background thread, and when you need to alter the UI, use SwingUtilities.invokeLater(Runnable) . I think you might find this tutorial helpful.

For the GUI, you should implement Runnable and use SwingUtilities.invokeLater(Runnable) :
public class Foo implements Runnable {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Foo());
}
public void run() {
...
}
}
In order to use images, you should use the ImageIcon class:
ImageIcon imageIcon = new ImageIcon("<path to image>");
or alternatively if you already have an Image object:
ImageIcon imageIcon = new ImageIcon(image);
then to display it:
JLabel imageLabel = new JLabel(imageIcon);
