Making Joystick buttons control moters

[Slothbron]

We where a rookie team last year, but we lost all of are programmers and the simple codes they made last year. I'm new to programing and but confused with some stuff. One thing I want to know is how you can program a motor so that when you press one button it makes the motor run one direction. But then when you press another button the motor moves the opposite direction. These motors are going to be used to raise and lower are arm and open and close the claw. Also we are planning on having victor speed controls hooked up to them is it any different to program them with the speed controls?
