Google released the GWT SDK 2.1 final that makes it possible to build just about any app you can imagine. "For the 2.1 release though, we aimed to provide a set of building blocks that will scale to support your entire user base, but at the same time are easy to piece together to get a web app up and running," stated Google.
If you're looking to start building apps using Spring Roo and SpringSource Tool Suite integration, quickest way is by downloading SpringSource Tool Suite and installing Plugin for Eclipse from main Dashboard component. Once downloaded, simply start up Roo's command line interpreter, and run "script expenses.roo" command.
This'll run a series of Roo commands that produce a starter web app. Now that a app is created and launched from the command line, we can import it into STS to start customizing it. Simply switch back to STS and click menu item File->Import, select "Existing Maven Projects". Once imported you can now run app directly from STS right clicking on project and selecting "Run As->Web Application"
