file.obj and opengl

Hello everyone!
I have problem with
import file. obj and save it informations in a data structure (using c++) and draw with opengl
for exemple
if we have
this file
http://people.sc.fsu.edu/~burkardt/data/obj/cube.obj
it must with the program c++ and opengl be
like this

Since obj files simply store polygons, it's pretty much just a file parsing problem. Taking the OpenGL step (at least the easiest way of doing it) after that is pretty trivial.
