Ok I have created a Guild Alliance Website and the response from our realm in WOw has been huge (856 members in two days). I need a quick way to associate rank between guilds.

Also it would be nice to have the ability to ad Ajax or something similar to pop up a larger window showing their Home page on their website.

I don't think anything like this exists in the system. Your best bet would be to get all GM's to agree to use the same ranking structure and thus only have 1 identical to all guilds and the site.
