This sounds like a good project. We're in need of higher level abstractions over
our existing GUI toolkit bindings.

Do please keep us posted with your progress at gtk2hs-users at lists.sourceforge.net
and if you have any things you want us to fix in the underlying gtk2hs library
or anything else to make your stuff easier then do come talk to use about it.

If it turns out well maybe we might want to distribute your wraper API with
gtk2hs be default.
