Arduino/Adafruit stepper control

I need a program written for a Arduino and a Adafruit v2.0 motor shield controlling a Adafruit Stepper motor.

Hardware:

Arduino Uno

v2.0 Motor shield

Push button

LED

The program would work as follows:

Push button (a first time)

LED turns off and the motor turns clockwise 50 steps and stops (release) and then the LED turns back on.

Push button (a second time)

LED turns off and the motor moves clockwise 50 steps and stops (release) and then the LED turns back on

Push button (third time)

LED turns off and the motor moves Counter-clockwise 50 steps and stops (release) and then the LED turns back on

Push button (a fourth time)

LED turns off and the motor moves Counter-clockwise 50 steps and stops (release) and then the LED turns back on

After the 4th press of the button the program reverts back to the beginning and we start over moving in a loop..
