Is gtk a viable GUI framework for use with C++?

["Karim Hernandez" <karim dragonshed com>]

Hello everyone,

I'm looking into developing some crossplatform (linux and windows)
opensource-ware, and I would like to use GTK for the GUI.  The prefered
language is C++ however, so I need to know if anyone out there has
successfully used it with GTK on both linux and windows. Issues with C++ on
linux asside, are there any obvious GTK issues I should know about?  Should
I be looking at a different widget set?

Thoughts, opinions, and other verbal abuse welcome :)
