I've been playing around with Google Forms (the new version) and I'm impressed. Its streamlined easy to use and unlike any other free form creation tool ( that I've found) it has Logic Jump (where you jump from one section to another based on your answer) and you can assign points to questions and create quizzes. There is not much customization yet but you can upload your own images and it's possible that in the long run they may add more.

embedding a google form into Xara is a simple copy and place.
