Tutorial/sample for feature builder?

Question

I am trying to use feature builder to mock up some guidance.. Specifically, on a standard C# class library, I want to add a context menu 'add myclass' which pops up a wizard to ask for a name, and then generates a new class, using a template, and that name. I also want to do a similar 'add mymethod' as a context on that class, with a wizard, that injects some generated method and updates web.config in another project -- ideally i also want to make a solution-level wizard to let me pick which project has the web.config, which supports myclass, etc.

I can't seem to find any tutorial/samples on how to accomplish most of this -- wizards, injecting methods, and global 'configuration' stuff are a mystery even after reviewing all the videos i could find on channel9..

Is what I'm after possible with feature builder? Can someone point me at how to do this?

Thanks in advance!
