Kit for wireless 8-button joystick? Answered

I have an application where I need to transmit 8 buttons of information to the computer..
I figure the best way to do it would be to use an 8-button wireless joystick kit (or similar)..
The software it will interface with will be an educational game on a PC,
so a joystick interface is perfect and I shouldn't have to code anything specific..
Are there ready-made kits to do this? I am fairly tech savvy..

Thinking down the road, bluetooth might be a plus since I could compile the
program for phones and use the wireless controller with phones as well..
