I'm pretty sure you need a bit of Objective-C to create the context and do other initialization stuff. The rest is also usable in C++.

Answer 2

In XCode, go to File > New Project... and choose the "OpenGL ES Application" template. That creates a project with great example code for setting up an OpenGL context and drawing into it with the usual C functions. Plus some other neat tricks like loading a UIImage into an OpenGL texture.
