How do I paint a TextArea or a Button over an Image

Question

I've started coding a game on Java recently, and I suck when it comes to GUI, so I've been having a lot of trouble.
The thing is:
1 - I have a thread object that calls repaint( ) at a 60 fps rate.
2 - I have a SimpleSprite object that can be created from this:
new SimpleSprite ( "image.png" );
3 - This same object has the following method:
public void paint ( Graphics g , int atX , int atY ) {
     if ( image != null )
          g.drawImage( image , atX , atY , (ImageObserver) this );
}4 - I have a JFrame object as my main program, and it has this code:
public Sprite background = new SimpleSprite( "img_bg.png" );
public void paint ( Graphics g ) {
     background.paint( g , 0, 0);
}Then, I can't seem to find a way to paint a TextArea or a Button OVER this background image on the paint method. And I seriously don't want to recode the TextArea class. It bores me to death just to think of how much would I have to validate at text-selecting when the font characters don't all have the same width.
Is there any way this could be done?

With this code you've just broken JFrame painting. I think it is better to create class-descendant of JComponent and do whatever you want in it's paintComponent() method.
Also, calling repaint() simply schedules call to paint() method. If you want 60 fps, may be " [Active rendering|http://java.sun.com/docs/books/tutorial/extra/fullscreen/rendering.html] " mechanism will help.
