How to create a facebook app?

Question

Facebook

Good afternoon, colleagues.
I am looking for advice in creating an application inside facebook.
The essence of the application is that people throw money for the sake of getting into the top within the application, transferring money to us. Just to be on the top 100 donor list.
Here is a detailed description of how it was implemented by the guys for VKontakte.

The purpose of the application is charity.
Thank you.
