Rewrite code from C# (VS) That gets Facebook ID/Token to a WebApp, So it can be ran from the Web.

Hello, I have a small C App that lets you login to Facebook (as an iOS Device) to retrieve back a Token and ID. I would like to move this to a webpage, from an .exe, this way it will be easier for people to use and trust. Also if you would write in Python3, that would be a huge plus. I will supply the C code in my VS project, if you know what you are doing, it should be very simple to do. in the C code i have it print to a file, there is no need to do that! just printing to the screen would be enough. Thanks.
