You can''t do anything useful with GLUT unless you use OpenGL, so it''s perfectly ok (that''s why it was made).

I''ve never used GLUT myself, so I''m not sure if this page is up-to-date or not, but you can still take a look at it: http://reality.sgi.com/mjk_asd/spec3/spec3.html

I''d personally suggest you use SDL if you''re making something you''ll distribute as more than just a demo. It is a cross platform game oriented library that does all that GLUT does plus some. It has 2D graphics built in, but you can just ignore those and use OpenGL with it. They have a reference to SDL linked on their page that tells you how to use OpenGL with it, and it''s pretty easy.
