A site called Hot Potatoes provides some easy-to-use software that makes professional-looking multi-choice and other quizzes. The snag is that "it is free of charge for those working for publicly-funded non-profit-making educational institutions, who make their pages available on the web. Other users must pay for a licence."

And the licence costs $120.

So, if you teach in a state school you might like to investigate. Otherwise, you can get the script for a simple quiz here.
