Yep, there are plenty of options for people who can't drum.
It's pretty easy to just tap in a drum track with BFD drums and reaper using pads on a midi controller too (there are a variety of preset patterns as well if the tapping is too hard). Or if you like planning out songs beforehand, free software like hydrogen drum machine makes putting together everything from samples very easy - that's usually how I write the rhythm parts for tunes I'm working on.
