I've thrown together an index real quick:

andrewhitchcock.org/gwidgets/

I only have a couple in there, but if anyone wants their widget include, just e-mail. The design is kind of ugly, but I'll work on that after I have some food. I might also try my hand at an automated widget parser, to load the information automatically from the widget's source. However, I wouldn't want it to get spammed.

Sorry to bogart your forum, but I created another widget that might interest you. This widget will allow you to keep track of your Alexa ranking right on the Google homepage:
