Google Web Toolkit (GWT) is a Java software
development framework that makes writing
AJAX applications like Google Maps and Gmail
easy for developers who don't speak browser
quirks as a second language. Writing dynamic
web applications today is a tedious and
error-prone process; you spend 90% of your
time working around subtle incompatabilities
between web browsers and platforms, and
JavaScript's lack of modularity makes
sharing, testing, and reusing AJAX
components difficult and fragile.
GWT lets you avoid many of these headaches
while offering your users the same dynamic,
standards-compliant experience. You write
your front end in the Java programming
language, and the GWT compiler converts your
Java classes to browser-compliant JavaScript
and HTML.News source:
