Aw: Trying to get the simplest communication between the client and server.

I think your code looks fine.

Do you actually have a MyGWTModule.html file inside your war folder or any html page that includes the generated .js files from GWT? 
If not you have to create one (New -> HTML Page. The one with the GWT icon). 
You can also create it by hand. Just make sure you have

<script type="text/javascript" language="javascript" src="<your module name>/<your module name>.nocache.js"></script>

in the html page's <head> tag and if you ever want to have history support you need

<iframe src="javascript:''" id="__gwt_historyFrame" tabIndex='-1' style="position:absolute;width:0;height:0;border:0"></iframe>

inside the <body> tag.
