Can Scala be used to write GWT applications?
(NOTE: Java/Scala novice here...)
I am aware of two projects that are addressing this issue.
Jribble(pronounced dribble) is a special form of java that does not have some of the human constraints of java so that it can be used for scala byte and still provide GWT with the information it needs to generate efficient javascript. They mention a github project called scalagwt-sample (http://github.com/rfc2616/scalagwt-sample) that seems quite active.
Another article I read had a guy using j2js(part of GWT) to cross compile scala to javascript. They won't let me put more than one Hyperlink but here is the url:

I have not had time to try either yet but hope to soon.
