GWT Beginner Tutorials

Hi everybody! I will use GWT in one of my homework projects and here are some useful beginner tutorials for GWT.
Btw, I am using java, not python..
google app engine getting sterted (an excellent starting point :) ): http://code.google.com/intl/tr-TR/appengine/docs/java/gettingstarted/
google plugin for eclipse: http://code.google.com/intl/tr-TR/appengine/docs/java/tools/eclipse.html, http://code.google.com/intl/tr-TR/eclipse/ (comes bundled with the App Engine and GWT SDKs)
google app engine sdk download : http://code.google.com/intl/tr-TR/appengine/downloads.html
java development server: http://code.google.com/intl/tr-TR/appengine/docs/java/tools/devserver.html

My very first step: (http://code.google.com/intl/tr-TR/appengine/docs/java/gettingstarted/installing.html)
Run the following command on linux:
./appengine-java-sdk-1.2.0/bin/dev_appserver.sh appengine-java-sdk-1.2.0/demos/guestbook/war
This is the command to run java development web server from the commandline. It takes the war location as argument. (war archive files are not supported by the SDK yet, so use a war directory for deployment. )The server can be run from eclipse debugger automatically.
Then examine http://localhost:8080/

to be contined..
