Any info how Lombardi's Blueprint is built needed

I've found Lombardi's Blueprint 开发者_JAVA百科as an example of applying GWT. It's awesome. I wonder how is it built, inspite of using GWT. What kind of widget and client JS frameworks did they use. Any info appreciated.

Lombardi are rather open about their experiences with GWT - they have a very good blog about it. They also gave a presentation on Google IO 2009 about it. Note however that some things are a bit out-of-date and, for example, could be done better/easier with GWT 2.0/2.1.

A video on InfoQ, I haven't watched it, so it may or may not cover the topics your interested in:
