Building a video server.

I have been given the task of building a video server that has basic video editing capabilities through a web interface. Something like what jaycut.com does. Right now we use FFmpeg on one of our servers to do command line editing and conversion but we want to make it super simple so that normal users can just upload videos and edit them.
So I am not sure if this is the right thread to start this in if not please point me in the right direction.
I have been searching on google on how to start this off but I'm really not sure how to do it. If anybody has any experience in this or insight to suggest to me that would be great.

Thanks!
