Adam Houghton has created a CoverFlow implementation for GWT called GWTFlow.

GWTFlow uses standard GWT widgets for positioning the images and callouts to Script.aculo.us for the effects. All of the photos are just Image objects placed on an AbsolutePanel, with a little math behind the scenes to determine positioning & simulate perspective. Albums & images are retrieved via RPC calls to a Java service, which then calls out to Flickr’s public API using flickrj. GWT made development & debugging a breeze, with history & cross-browser support basically coming for free.

Thierry Ruiz is using GWT in his site called dotemplate which is a free, online web template generator. The stylish looking control panel used to customize the web templates was created using only basic GWT widgets.

John Gunther has released his which is a GWT based charting solution. Be sure to check out the gallery to see what this library can do.

The slick looking MyGWT library released it 0.3.0 alpha 1 version yesterday. There are several API changes that may break your existing code. Unlike previous versions, MyGWT now handles events in the standard GWT way.

Michael Galpin’s four part tutorial on XForms and GWT is now available on the IBM developerWorks site.

Part 1: Introducing GWT’s JavaScript Native Interface
Part 2: Creating an artist and album management form
Part 3: Using GWT to create XForms
Part 4: Creating interactive forms with GWT and XForms

For those not familiar with the technology, XForms is the next generation standard for building HTML forms. One of its strengths is that it enables the separation of your form’s business logic from its presentation. So check out these tutorials and learn something.
