Ok, then you'll have handle translations to set your spheres at their expected locations. If you use the fixed pipeline, you'll have to understand how the model-view matrix works (glPushMatrix, glPopMatrix, glLoadIdentity, glTranslate), you don't have to modify the vertices when you want to move a sphere, you call glPushMatrix, glTranslate and then glPopMatrix. If you use the programmable pipeline, rather use Xerxes' example I quoted earlier. If you understand the concepts, it will help both with the fixed pipeline and the programmable pipeline. Have you ever read the OpenGL red book?
