How about starting with a  decent book or tutorial
Please check out 'OpenGL Programming Guide', from Addison-Wesley
and it's surely worth to have a look at the nehe tutorial:

and maybe the freeglut project:
file:///usr/share/doc/freeglut3-dev/index.html

and this may give you some other good hints
