Great, does it run well on Windows and Mac platforms in addition to Linux platform which should run fine?

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. :-)

Great. Well thought out design :) Other possible backends would be FLTK, GLUI, XBMC/Boxee (for set-top box apps) as well Qt and wxWidgets. I guess backends using Win32 API/Cocoa and FLTK would be the least bloated ones.

I am planning to create video phone software and I was looking for good GUI toolkit that supports FRP so it looks like it is right time to use Grapefruit :)

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.

Awesome! I'll be looking forward start using Grapefruit soon! :)
