I\'m building a Google Apps Chrome App (not extension but app) with gmail, calendar, etc.

Extensions in Chrome Apps aren't available by design. A webview is meant to facilitate displaying web-based content that you control, in which case you'd have the ability to alter that content at the server, rather than relying on an extension to do so.
Incidentally, you should take note of the applicable terms of service, which won't let you publish the app you've described in the Chrome Web Store: "Do not post an app where the primary functionality is to link to a website not owned by the developer."
