That would be nice.  But i think SDL (and ClanLib for that matter) don't
have any toolkit to handle menus, buttons etc; so you would have to
implement all of those by hand.

The WxWindows GLCanvas widget comes with a .lwo object loader (see the
'penguin' sample) it is under the GNU GPL.  Porting it to GLUT or whatever
should be easy.  The WxWindows site is at: http://www.wxwindows.org.

Yes, GLUT is a bit basic, beyond that it supports a few primitives ala GLU
(including a teapot!) and text.
