The WebGuiToolkit (WGT) makes programming rich web applications with Java as simple as client-side programming. 
You donÕt have to code JavaScript, XMl, HTML, CSS and so forth. WGT is a framework where you code your web application 
like a desktop application with Swing or SWT. It is mature Ð we have been using it for quite a while for our professional 
web development.
