I do some recording by running my guitar into my sound card through a 1/4 inch to 1/8th inch jack that I bought at Radio Shack (2$). I usually use cool edit pro (because it's easy to use and can be downloaded for free (with a crack) from a bittorrent dump site) for most of the editing/recording. That's how our band develops songs and stuff. It's not pro quality sound, but definately good enough for little demos . . . you could also look for an adapter for a mic (to plug into your computer) if you have a good one kicking around . . .
