where Apple says of it web developer programme:
"Extensions made simple.
If you know how to develop web pages, then you already know how to make extensions for Safari. And help with putting it all together is built right in. It’s called Extension Builder, and it makes it simple to package your extension for distribution and installation. Instead of manually entering your scripts, menu items, stylesheets, and commands in a complicated text file, you can select your extension resources visually in a template that’s as easy to fill out as a form. You can also use the built-in Web Inspector to design, debug, and optimize your extension, just as you would a website."
Have a look.
