I know what you mean - a friend of mine comes up with ideas like that too, but she doesn't know how to code and doesn't even have friends who do.
She even asked me if I knew anyone and it's not really that simple. There must be some sort of crowd-sourcing site for budding coders looking for things to collaborate on or practice their skills?
I guess the thing is it's probably not as simple to make as it is to come up with the idea, which means we're into "this is a serious project" territory. Hard to get into something like that with strangers.
Good luck anyway! If I come up with anything I'll post here.
