Here, try this. In the GLSLExample replace all the:

try:
   # For OpenGL-ctypes
   from OpenGL import platform
   gl = platform.OpenGL
except ImportError:
   .....

with:

gl = ctypes.windll.opengl32

The example expects the pure Python OpenGL 3.0. If it doesn't find it it 
falls back on a bunch of Unix specific searches. Windows os functions 
use the standard calling convention, which differs from C.
