paint method hides disabled JButtons

Whenever I want to add a disabled button, this seems to work as intended.

public class ButtonDemo extends JPanel {
    private JButton b;
    public ButtonDemo() {
        b = new JButton("Button Demo");
        b.setEnabled(false);
        add(b);
    }
}

Here's the result:

But whenever I add the

public void paint(Graphics g)

method, the disabled button disappears.

So is there any way I could have both the paint method and the disabled buttons because I need to use the paint method to add text above the buttons.
