An Application submission scenario

Hello,

imagine a school Contact Forms 7 application scenario, where a visitor sends an application, which gets forwarded to MORE THAN ONE person. One, and ONLY ONE of those persons needs to reply, and user who repeat the application should be ignored.

Two problems arise:
– coordinating between the group of recipients is complicated. So, users frequently get MANY replies (Some of them contradict each other)
– the form is not smart enough to catch people who apply more than once, even when they have a UNIQUE user ID that repeats itself in multiple submissions.

So, here is what we would like to do.
– Have people who need to respond go to a private page in the web site (easy)
– Show in that page all previous submissions, sorted by the UNIQUE ID. (That way, repeated applicants easily show up)
– Add a field where the user who responds can record the event (binary field, yes/no). That way, when the second person is about to respond, she can see that it’s not needed any more.

Now, the question:
Would it take a lot of coding to do what we want? We don’t have too much technical expertise, so unless it’s something simple we could not wing it.
