How to convert .mov to .wav?

Greetings,

I just produced a promo video for a non profit event in imovie. Now they want to include it in a mass e-mail. They are unable to read any of the formats imovie puts out on their silly pc's. Somewhere on a forum I read that Quicktime pro will convert.mov to .wav.... $30 later it turns out it doesn't.....

So, how does one make imovies visible on a common PC, ie using Windows Media Player......

Thanks.
