Somebody might have posted this befor me, havn't read all thread.
I just got a bluerooth-USB thing for about 10$ and then installed the program "BlueSoleil" that i got with my bluetooth-USB thing, then i downloaded a program called "GlovePIE" which with the right script can "convert" the wiimotes buttons and movements into keyboard buttons and mouse for your computer.
You can aslo use the Nunchuck when its connected to the wiimote
I've done it many times, tho its very boring
