One month, sure :D Realistically, if you have no GPU or OpenGL experience, to build something like that, lightning, shadows.. And to really understand what is happening, in one month maybe if already know C++/your language of choice well, you can grasb the idea of how to draw a triangle with maybe some lightning.

Shadows, animation, no way in a month. The whole OpenGL stack is pretty complex.

My suggestion would be the same though, but maybe reserve one year to really just grind the basics until you have a clear understanding of what is happening.

On the other hand, if you just want CUDA, there are frameworks for that for enabling parallel calculations without having to understand graphics programming.

Yes I am simply concentrating on parallel calculations and I dont need any graphics to work upon
