Originally I was thinking of using GTK, since it has the option of using other widgets along with the GtkGLArea to be able to make general applications with GTK and have the option of adding on graphics. Though that seems to bring up the KDE/Gnome flame war out of no where. Also it requires OpenGL 3.0 or higher as OpenGL 2.0 and lower has too much legacy code to work with. Makes sense, though I still don't know how to use VOA's effectively.
