Google's next Open Source project
A prediction: In a few months time Google will release a project called 'GDT'. GDT is somewhat similar to GWT except that rather than compile Java to HTML+JavaScript, it will compile to Swing. So rather than being Google Web Toolkit, it will be Google Desktop Toolkit. You'll then be able to take the same source, and get out of it either a desktop app, or a web app.
While we're on the subject, the same idea in reverse: I wonder if anyone at Google is working on having JavaFX compiled using the GWT compiler?
Re: Google's next Open Source project
Joe, we released IBDOM a few weeks back, which should nicely complement DWR and some other frameworks, we could use your feedback/thoughts/suggestions. If you have some time ... please ping me :)
The 0.2 release is coming out soon, which will be the version we're using in production in one of our customer-facing DWR-driven applications.
Re: Google's next Open Source project
This is totally improbable, given how everything your write with GWT relies strongly on the DOM, namely CSS. The only reasonable way to get a desktop app from GWT source is to embed a browser instance within it that will render the UI. Why would you want a Swing app from GWT source anyways? This is way too little demand, if any, for such a feature.
What would be a lot cooler is having GWT compile to Flash.
