Multi-Color Buttons?

["Schumi Imor" <schumiimor gmail com>]

Hello,
   I'm new to GTK+ 2.0 and would like to get some ideas or expert advice on
how to do or if this is doable.

I have a button (vertically-rectangular shaped with 3 lines = shown below),
line 1: a letter, line 2: a seperator "---------" line 3: a letter. What it
the best way to make this button become multicolored where the upper half is
1 color and the bottom half is another color and then there would be no need
for a seperator?  Divide this buttom into two? or is there some API to
manipulate things at the button level? All ideas are appreciated...

Thanks
