Pending Comments Bubble Number on Front End

Is there a way to show the pending comments bubble number on the front end of a site?

There are plugins like - http://wordpress.org/extend/plugins/wordpress-admin-bar/ but I don't want to use a plugin, I've coded a simple html and css admin bar (borrowed css from buddypress admin bar, I don't use buddypress) in my footer template file and want to show the blog admin (in Multisite) whether there are any pending comments via the bubble from the back end.

So just hoping there's some php function that can call the 'bubble' into the front end.
