Sure, why not! Wipes can even fix bad sizing/cropping or camera angle between shots. They’re a little less jarring than smashing to black, but far less jarring than a jump cut (although some jump cuts are done deliberately to good effect, as in the opening sequence to Dexter).
Another free animator would be Virtual Hub and MonkeyJam, although I dont know how to use Virtual Hub well, and I’m not good at MonkeyJam either. For the Mac,iMovie is what people use. There is also some good programs that come with a price, the best being iStopmotion.
