building a plugin with a toolWindow. newbie is stuck

Hi everyone.

Im wanting to build a plugin for phpStorm that is another toolWindow.

I have built what i want in php here:
http://junk.hostsaba.com/index.php?pg=projects&t=list_all

Its uses RESTful API to communicate with my other site solo-developer.com

The finished product will hopefully allow me to interact with my site from phpstorm.

The probem.  This is my first project in Java and I cant seam to get to the start programming point.

I tried to follow the steps to get the 'Sample Tool Window' to work in the Community Edition.

using Intellj Community Edition IC-117.216  I have copied the /samples/toolWindow to /plugins/toolWindow  and 'Create a new module from scratch' on that directory.

When i click the green arrow "Run IDEA" a new instance of intellj starts.  it is "intelliJ IDEA (Community Edition) IC-118.SNAPSHOT".

The "Sample Calendar" toolWindow button does appear in the right hand margin.  clicking it does open a tool window, but there is nothing in the tool window but "Initializing..."

The event log shows:
6:34:51 PM ClassNotFoundException: MyToolWindow.MyToolWindowFactory PluginClassLoader[Sample Calendar, 1.0]: MyToolWindow.MyToolWindowFactory PluginClassLoader[Sample Calendar, 1.0]

What do i need to do to make the toolwindow work properly? (and any other pointers that you think i should be reading would be appreciated.)
