ulead video editor is the easiest one i have used so far if you just want to cut video , then vcd cutter is the easiest one
Final Cut Pro X is one of the best I've known of. Adobe's tools will do the trick too ( Adobe also has tons of videos and free webinars to help you with learning more about the tools).
Have you tried pinnacle studio yet ? EDIT: Actually, I'd say that Adobe Premiere Elements 11 is pretty good and should be easy to use. I for one have never used it, but based on its reviews, it looks good to me. Pinnacle studio also is great, but I feel like its interface is a whole lot harder to use. Then again, I could be wrong.
