Actually, I have no idea. ;-) 

Well, Grapefruit is a pure Haskell library without any own binding to C 
libraries or whatever. For GUI stuff, Grapefruit relies completely on Gtk2Hs. 
So if Gtk2Hs works, Grapefruit should work too. I just haven’t tested it so 
far. Earlier Grapefruit code was successfully executed on the Windows box of 
my co-developer.

On the other hand, Grapefruit is designed to be implemented on top of 
different toolkits, although currently there is only the Gtk2Hs backend. So 
if you want to write a backend based on the Win32 API or Cocoa, this would be 
very welcome. :-)

This would be really great. Writing applications with Grapefruit gives me 
useful feedback and pressure for improvement. Note that currently the set of 
supported widgets is very low but this is likely to change during the next 
weeks and it should often be very easy to port Gtk2Hs widgets to Grapefruit.
