I'm thinking to use GWT for my future projects because I like what I'm seeing. It also has solid integration with other Google APIs + offerings (like Google Gears).

My only concern is the HTML output. It seems to me that the output has tons of divs. Certain widgets use Table based layout. It certainly feels like doing ASP.NET.

While the JavaScript output is highly optimized, maintaining the HTML seems to be a little bit out of the question.

While I don't mind to learn JavaScript, I have the feeling that it'll take some time for me to learn it before I can actually use those frameworks (jQuery, Prototype, etc) for serious/professional work.

Any thought on this?
