In case you haven't seen it, which you probably have, there is this. But it is complicated, but I've seen one in action and it went far, really far.

Trebuchets really aren't that complicated. I built a computer-targetted one for my senior project. They're simpler in that they don't use tension; they use a counterweight instead. The only real hard part about them is getting a proper sling design.
