The Google Web Toolkit (GWT) is a new technology from Google that automatically translates Java into JavaScript, making Ajax applications easier to code and deploy.
As you might have guessed, it emphasizes end-user experience, GWT usability features, and several of the big improvements made in GWT 1.4 RC.

Usability = Great Application + Happy Users
The Web is experiencing a new growth with an emphasis on rich, web-based applications. These applications can be difficult to build because they rely on JavaScript, which lacks the sophisticated object-oriented structures and static typing of Java, they are tricky to debug, and they require you to manage numerous browser inconsistencies.
In May of 2006 Google released the Google Web Toolkit. GWT enables developers to create Ajax applications in Java. With GWT, you can build your applications using a real object-oriented language and take advantage of Java tools like Eclipse that are already available. Instead of trying to bring tool support to Ajax, Google brought Ajax to a place where the tools already existed.
