I don't know of any web interfaces and it may be fairly easy, but not as simple as you might think. Some packages ask questions. I think dpkg-www may handle those, but I'm not sure. Alternatively, I guess you can tell debconf to never ask anything and hope for the best.
There are various systems capable of remote control, including puppet and cfengine, if you want to initiate updates yourself.
I guess seeing as you wrote "servers" that the desktop frontends from the likes of ubuntu aren't an option. I'm not sure of the current state of webmin, but it might work: http://doxfer.com/Webmin/SoftwarePackages#Updating_on_Debian_Linux
Hope that helps,
