How much of the http://www.sheldonbrown.com/gears/ wheel needs to be reinvented?  It works in every browser I've tried it on, including a couple of Android devices.

The calculator app should do the trick. Divide the ring teeth by the cog teeth and multiply by your wheel diameter.

That only gives one gear at a time.  The Sheldon Brown "app" gives the entire gear chart.
