PyQt works fine with PyOpenGL. The QtOpenGL module only provides
widgets and other features for use with an existing OpenGL library.
It doesn't provide or expose its own OpenGL implementation.

For example, you would typically subclass QGLWidget and reimplement
the initializeGL(), paintGL() and resizeGL() methods to handle
initialization, painting (with PyOpenGL calls) and updates to the
transformation matrices. Since QGLWidget is itself a subclass of
QWidget, you can use standard PyQt code to handle user input
and other non-OpenGL tasks.

Take a look at the examples provided in the PyQt distribution to get
started.

Good luck!
