GWT (formerly the Google Web Toolkit) is a development toolkit for building and optimizing complex browser-based applications. Its goal is to enable productive development of high-performance web applications without requiring the developer to be an expert in browser quirks, XMLHttpRequest, and JavaScript. GWT is used by many products at Google, including the new versions of AdWords and Groups. It's open source and completely free (Apache 2.0 licensed).
