I would start off with a 2-D game first. Making a 3-D game involves a lot of linear and vector algebra, and can be a daunting task for someone just starting. You can try something like a simple 2D shooter as your first game. Do you already have experience programming in Opengl?
Ezzaral makes a good point, out of respect for others please type in full-sentence English. As for "helping you in", there are several good tutorials for OpenGL, namely the site Ezzaral referenced. It's going to take a lot of dedication and hard work if you want to make a game, along with a lot of learning on your own. If you are waiting for someone to teach you how to use OpenGL you're going to be waiting a long time..
