This document discusses Google Web Toolkit (GWT) and Google App Engine (GAE). GWT allows developers to write code in Java that compiles to JavaScript, enabling Ajax-style web development without browser plugins. GAE provides a scalable hosting environment on Google's infrastructure. The document outlines benefits of both technologies, such as reusable components and easy management, as well as some limitations like the single-threaded model. It also provides examples of using GWT widgets and GAE for persistence in web applications.
