Here are several things that I have decided to read. The progress will be exhibited here.
GTK+, a light GUI library, we have a pieve of tutorial for GTK+-2.0 and related FAQ. A C++ wrapper is provided, with the name Gtkmm. They kindly give us an API documentation and its FAQ. There is an OpenGL interface for GTK+, called GtkGLExt. There are few materials on it yet. I have to find more later on.
