If you go to your guild page at http://www.guildox.com/wow/guild/us/Gundrak/Equinoctis
you will see tabs for Pics, Banners and Sigs. These give you various live widgets that show your guild's raid progress. The code is provided for HTML and BBCode to make it really easy to add.
As for the raid progress widget for a realm - no, we don't have this but it might be something we can create. Leave it with us.
