I've been looking for the same thing. I've noticed in the C::B RC2 version, one can go to Project -> Properties, go to the Targets tab and change the drop down menu for type to console application. It still runs the OpenGL app, but the black command-line console appears in the background. A simple cout statement can give output through it and I suppose input will work as well.
Now I need to figure out how to adjust things so that the console window appears by default with every OpenGL project, without having to change it every time.
