Although 90% of this forum will scream at you "Learn to program! Do it yourself!", if you really want to just use someone else's engine, there are a few around. There's Miles Lombardi's although I think that's GM5, and of course there's my old one here:

Although inevitably, if you're not the creator of the engine, and as you say if you have little programming skills, you'll probably find other people's pretty difficult to use.
