the problem is Apple. if you want to have a native gui on OSX then you are either nearly stuck to Objective-C or to obsolete gui libraries.
i'm not a mac user, but i know one who is; he told me.
on osx there are two main gui apis: carbon and cocoa.

carbon is obsolete, but it partially runs on osx -- it is not 64bit compatible.

cocoa is the newer one, which every mac user likes.
AFAIK there is no C backend to that api, so you will have to develop a C backend first and then the haskell (or gtk2) wrapper.
there are some bindings for other languages, i.e. C#, but no C.
<http://en.wikipedia.org/wiki/Carbon_%28API%29>

if you are able to code objective-c and know how to access cocoa using c, please help those gtk developers to port gtk2 to native OSX.
it will then automagically work with gtk2hs.
