Whatever happens to Google Wave, its UI, in my opinion, is 'beautiful'. In fact, it's listed as a real world project that utilizes GWT on GWT's web site. I would like to learn how Wave was built using GWT, but there does not seem to be many documentation on that topic.
Could anyone please point me to the right direction with regards to documentation or show how that the Wave UI can be built using GWT.
Update: The question is how build the UI and not Wave itself.
You can browse through the reference source code and see how that's using GWT.
