Luci Bridge App....did someone already made an initial build?

I would like to see if I can make a Luci app that will let the user configure the complete linux bridge. So basically whatever I can do via "IP" and "BRIDGE" commands in a simple GUI.

Additional features should include the ability to set (different) DHCP settings for various VLANs that get configured using the GUI.

Did someone already made this, or has some initial effort that I could use so I don't have to reinvent the wheel completely??
