Logic is only on mac, but if you look around on sites I am not allowed to link to you should be able to find Logic Platinum 5.5 which is the latest PC version. Cubase is also really good, and so is Sony Acid Express. About simplicity though, tbh, they're all complicated IMO, but I to am a beginner and only ever really used a computer to record and fine tune, and never really sat down in front of it and thought I could use it to make a drum beat.
