I was able to create, for example, a derivative of the GWT TextBox (textfield) that, instead of creating one, captires one already on the page effectively making it a GWT widget. But the event hookup is incomplete so far.
Have not figured out yet how useful that is but I could see that kind of widget GWT-ifying form fields rendered by Tapestry. I guess at the very least you could write client side validaters in java (which would be cool indeed). Right now I'm in yet another death march at work but when I get a minute away from that, and Spindle 4T4, I'm going to see if I can change the autocompleter widget I wrote last weekend to add autocomplete to a text field captured from the html.

Geoff! Please drop a hint on how you think GWT could be integrated with tap.
