You could also try to generate the needed HTML on your server and send it to your client. On your client you could put that HTML into a custom Widget via setInnerHTML. This custom Widget can overwrite onBrowserEvent if you need some basic event handling for your generated HTML. We did something like this for generating questionnaires on the server (questionnaires are defined through xml and stored in a db) and intercepting events whenever a user interacts with a checkbox/ radiobutton/textbox. We primarily did this because of IE's poor performance. If you use any other browser then I would also send some sort of custom data object to the client and use this object to build the UI.
