I agree about API driving implementation - but would point out that in
general, the more you can reuse of the existing widget set, the less ATK
you have to reimplement.  If you use (even a subclass of) GtkCheckbutton
as a child of this widget or even an internal implementation detail
(that doesn't look like a normal GtkBin child), you can reuse more of
GAIL by just proxying the ATK stuff from gailcheckbutton out through the
expander's ATK interfaces.

You will have to make that call; for something like checkbutton it might
not be a big deal, whereas reimplementing something like AtkText or
AtkTable would be a big PITA if you had the choice of reusing or
proxying an existing implementation instead.
