How do I create a custom floating Swing component without a JFrame?

Question

I'd like to create a custom swing component such as a desktop widget which does not require a JFrame (or to extend it) to be printed on the screen.

I don't want to extend the JFrame because my component is really simple and JFrame implements a lot of functionality I dont need.

Who do I start? Which class should I extend?

Many Thanks

EDIT ---------------------------------------

Thanks guys!

I'll check the references you sent. Also, is it possible to java to draw on the screen without swing API?

If you don't want the functions a JFrame provides and just want floating graphics then use a JWindow. It does not have window decorations.

Example with plain label in a JWindow:

public static void main(String args[]) {
    JWindow w = new JWindow();
    w.add(new JLabel("Testing a Window!!!!!"));
    w.setLocation(300, 300);
    w.pack();
    w.setVisible(true);
}
