I have bundled the ExtJS theme "2brave" (created by wregen, details here: http://extjs.com/forum/showthread.php?t=46589) for ExtGWT. This easy-to-use JAR file can be used the same way as "Slate" theme described here: http://extjs.com/forum/showthread.php?t=41727.

And then register the theme as follows:
The attached file gxt-theme-brave-1.0.zip needs to be renamed to gxt-theme-brave-1.0.jar and then included in your ExtGWT project.
