I mean, it depends on your hardware in a lot of ways. If you're using something like on this page http://www.cheetahdeals.com/Refurbished_Laptops_s/... then your choices will be somewhat limited. There are some free programs (like Anvil Studio) and if you buy any extra hardware, music creation software is generally bundled with it. That's not a bad idea, because it usually helps to have some sort of controller or keyboard. OTOH, you could get an Apple computer. They're bundled with GarageBand, which is pretty straight forward.
