I took a training flight last year in a Cessna (by no means does that make me an expert).
Flying the plane, turning, etc. was pretty simple.
Taxiing on the runway was harder than flying. Getting used to the brakes and turning was the hardest part (but at least I stayed on the taxiway

).
Taking off and landing (I did not do those things) would probably be the hardest part. In a low-wind situation, I think I could probably do it (like someone said, it wouldn't be pretty), but with higher winds or a crosswind, I'm not so sure.
