Hi Bill.
As much as possible the widgets in the toolkit use the DOM class, a helper class which is used to interface with the HTML DOM. Packaged in GWT there are several versions of the DOM class, each specific to a browser(s). So, if you are lucky, you will only need to create your own DOM implementation, specific to your browser, alter some config files, and everything will work just fine.
On the other hand, things aren't always that easy, so it hard to say without the specifics of the browser you wanted to target.
