Cross Platform C++ GUI Development

[Matt Patterson]

Hey everyone,

I am interested in putting a gui on some code I am working on. I intend 
to make the code open sourced once it is at least alpha quality, so I 
want a nice gui toolkit that will work on windows and linux (and 
hopefully mac ox x). I havent done gui since Borland Delphi Builder, so 
please point me in the direction of the tools and tutorials I should use 
to get things started.

Thanks,
Matt
