Hi I have stepped into the world of the pics

basicly I have a knowledge of electronics but I just started out using pic micro controllers.

I wanted to use a pic 16f84a to control leds and servos wirelessly

now I know I need a transmitter and a receiver but for the programing what codes would be used to press a button or turn a potentiometer and have a servo move or leds turn on or do a sequence I programed for the leds or the servo.

Would this have to be done through serial and if so is there any other ways?
