Making a game controller using the Arduino uno

Hello all
I am looking to create a game controller using the arduino, a joystick shield (from sparkfun), and a bluetooth dongle (also from sparkfun). I am sort of lost on how to do get the bluetooth dongle on the arduino to output something. I want it to output a button press, sort of simulate an actual keyboard. Would anyone know of any good tutorials?

SF sells about 15 different BT and a dozen different joystick devices. The first question
to answer is .... How many ways can you combine 27 different devices, two at a time?

I am using this shield SparkFun Joystick Shield Kit - DEV-09760 - SparkFun Electronics

Have you considered the Arduino Esplora?
