The buzzword circa 2006 was "Rich Internet Application" framework/platform and the concept was not even totally new then. It included GWT, but also an Adobe product built on Flash called Flex and some other vendor solutions that compiled to Javascript that I no longer recall the names of. The space was well-defined enough that there was a Gartner magic quadrant for it.
I had a big interest in RIA at the time. The big players were Adobe AIR, Microsoft Silverlight, Eclipse RCP, Netbeans, and I also considered JavaFX--I might be forgetting another one.
Silverlight had the best performance/fit for my purposes and sadly was the first of many to go away, largely due to the popularity of iPhone and these platform/tools being excluded. Too bad Apple only promotes Apple's innovations and actively suppresses others.
