Create a new module for International Checkout payment module

[icecold]

LOL - sounds like it is absolutely interfering with the standard checkout process, by bypassing it entirely!
I don't know how GC does it.
The PayPal button is simply drawn within the template where it's required.

Lol, it does

ok, so that's std way GC process_button() is empty!

BTW is there an easier such as writing the code in a separate file and require it or inside the class?

Because in my case I just need to write button the way Paypal does, but there is no need for a handler.
