I'm with the OP on the 100's of badly implemented, slightly-sucky UI components. Cappucino did this brilliantly... but it was a too big paradigm shift. Give me a beautiful UI library written with elegant and performant JS behind the scenes, but let me implement stuff in a non-desktop way using standard web technologies. I like the concept of GWT, but Cappucino fell into the ExtJS/Sencha category for me - trying to reinvent the web using web technology.
