Blackberry custom ButtonField with icon and text

How would I go about creating a custom ButtonField that includes an icon? I have found several different sources for a ButtonField with a custom background Bitmap, but I want to have a button with an Icon and text under it. I can not find anyt informaiton about this, maybe someone here could help me out?

Cheers
