Widgets GWT, newbie to rails

Hi. I am investigating different tools to make my first ajax website.

First thing I tried was Google Web Toolkit, which I managed to get working fairly Ok. Once I did all the finicky XML config files and everything. The hardest part was trying to position the various frames and widgets which was a real pain - didnt seem to act the way I thought it would. GWT is very poorly documented. Also I had a heap of pain trying to get my test app working on an external hosted server - to the point where I gave up and resolved to try RoR.

After skimming through the online 'Agile development with Rails' I am a bit confused about how I do AJAX type controls with RoR. This was the strength of GWT for me. Knowing nothing about RoR, I expected to it to have 'widget' type functionality built right in - reuseable ajax controls..all the work already done. But this is not the case?

Is there some kind of summary of using RoR for ajax websites that starts dumb but goes into good detail about how to do it? because if I have to write my own widgets, Im really not interested. I dont know anything about html or javascript and I dont want to know.

I just started with ror myself but I’ve done some ajax work. These two sites have proven invaluable to me. So I hope this will get you going.
