Welcome to the Community!
While we wouldn't be able to host an app of that sort for you, you may be able to achieve the "instant gratification" by integrating the app to respond to an API and/or IPN signature. We have full documentation on these features, including developers such as yourself who have already integrated working solutions to very similar problems, on www.x.com. Give it a look - I think you'll like what you see!
