If you are willing to pay a programmer, they will write anything you want. I am not sure what the question is here. If you really wanted to, you could personally pay a freelance programmer to write any application you wanted.
The question is, do you really want it bad enough to come up with the cash? Or per your group idea, can you get enough people interested to donate the required funds.
Of course, it is better to have somebody who truly has an interest in the product or project to donate his time to writing the software, rather than paying somebody for a one-off assignment they won't update or manage after the fact.
