If it has a stereo out, just take a stereo cable that goes to an 1/8" stereo male end and plug that into your audio card's line in. Set the correct input for record, press record in your chosen recording program, press play on the 4-track. You should be getting a level then.
Go from the LR line-outs of your 4-track into the LR line-ins of your computer. If you don't have recording software, I think windows has a Sound Recorder in(Accessories/Intertainment) that you can use (although I've never tried it). Once you have it recorded in digital format, you can use your CD burning software.
I was quite happy with the word help. It was everything after that I had trouble with.
You don't mention what kind of 4 track you've got. If it has digital out (s/pdif), and your sound card has s/pdif input, then that would probably be the best way to transfer the audio as you're skipping an A/D conversion
