I had the same problem with not being able to get my tire back on, until I took a flat fixing class with the luna chix. I have carpal tunnel so I just couldn't get the freakin' thing back on, but the teacher showed us how to do it pretty much like Deb says, squat (or sit) with the tire on your knees to get leverage, and use the meaty part of your hand to push the tire in. That was the most helpful part- before I was using my fingers/thumb to try to push the bead in. Gripping the other side of the rim with my fingers and pushing the tire in with the meaty part of my hand worked! First tire changed, 6/20/07 at around 9 pm (in that class). I actually cried I was so happy.
