You should read relevant tutorials, they are easy to find using a search engine like google.

OpenGL is a low level graphics API which requires you to do many calculations in your own code, there is no "zoom API". If you want to have higher level APIs you could look at, for example: JogAmps Ardour3D continuation, or jMonkeyEngine.
