Just a word of warning, but learning C++ from books and online tutorials will be very, very frustrating. If your aim is to make a 3D game in C++ then prepare for many years of hard work. OpenGL is actually a great API and once you know a fair bit of C++, will be able to get some cubes and spheres moving about without a problem,(The Win32 API, however, confused the hell out of me.)
The problem starts when you want to load things like textures and models. In Blitz, this can be done with one line of code. In C++ it can take a few hundred lines. Then, if you want to move those models around and interact with them using your mouse, you'll need to learn Algebra which is a task in itself.
Anyway, I think if you're really set on learning on C++, you should enroll in a course where tutors can give you assistance. Just my two cents worth.
