Excerpt: The GUI designer tool that has been building your GTK applications for years is back with a completely new generation of homegrown free software. Supporting all the widgets in the gtk 2.8 familly, gnomeui widgets, the gnome canvas widget, and a whole new feature set; this new tool is sure to raise a few eyebrows.
This thing is awesome!! Its basically a WYSIWYG GUI creator for all your GTK apps.
