well, there are several commercial solutions to the problem out there, and also some freeware applications that can help you out.
another way would be to buy one of those turntable-to-mp3 with built in casette dech.
anyway, I haven't tried any of them myself yet, so I can't really recommend any.

Audacity will do what you want and it is free - you will need a line out from your player to the line in on your computer.
Without line out/in you can use earphone out and microphone in but watch your levels.
