For fully integrated sites like google docs, you should see things like Dash integration:
After the site has been added you can launch it from the dash, or add it to your launcher, just like other applications.

- Developer Getting Started - if you want to integrate directly from your web application.
- Developer Tutorial - if you want to write a userscript to support a web application.
