How would I create a theme setting event receiver for Sharepoint 2010?

Question

Currently we have a custom theme applied to Sharepoint 2010 main page. When a new site is created, it has the default theme. We would like all newly created sites on this Web Application to use a specific theme that we specify.

I would like to create an event receive for Sharepoint 2010 that sets a specific theme when a new site is provisioned. I am unsure of the code that would be used to acheive this.

I am currently using Visual Studio 2010 (with limited coding experience).

In the past I have created theme staplers using code from the following source.

Any help or pointers would be greatly appreciated.
