For .NET projects here's how you can create item templates, and this would then be available in new document dialog.

For Visual C++ projects you would need this:

Hope this helps.

Actually that is exactly how you add a new file type. You create a new item template with the extension type of .st and then you associate that file type with visual studio using the file association option in the customize menu.
