How do I overlay a JLabel image with text?

I am extending the JLabel class using the JLabel(ImageIcon imageicon) constructor.
What I would like to do is put text directly in the center of the label, directly overlaying the image itself.

I have tried code like the following, which does not seem to work:

public void paint(Graphics g)
{
  super.paint(g);
  g.drawString("some text", 5, 5);
}

the JLabel itself is about 20 x 20 so I would think that I would at least see something. Thanks in advance for any help.
