I need to have a player controlled by a controller for a game i am making.

i have yet to ever program the use of a controller into a game and need to do it for a game i am currently working on. I don't have to much of an idea on how it works or what i need. so i ask of anyone can help me out and teach me how to do so. I am going to be using a xbox 360 controller, all i need to do is be able to move forward backward and look around in a 360, up and, down. Help would be greatly appreciated!!
