Allow users to add their own site google analytics/adwords reports

So, users of my site would be able to enter their google accounts, select multiple profiles and see google reports of their own sites. and click between the profiles to review their own site statistics
Also, how would I get adwords info into this 'hypothetiocal' site?
1) Was going to use iframes but google have disallowed their content within iframes
2) Not good enough to write my own API modules.
3) looking at external links into tabs on the browser at the moment with a drupal 'control panel' to switch the tabs into focus, but seems clunky at the moment.
Thoughts?
Cheers
