I need to use a JPanel as a JButton

Question

We have a requirement here to display a panel full of various text fields and colors, but have it act like a Button. Focus handling, click handling, etc...
Anyone know of a JButton class that lets you use a JPanel as it's content instead of just a text string or icon?
