Payment gateway with Java, PHP or ASP.NET

Hi. The payment gateway for debit card in our country only works with Java, PHP or Has only of the members being able to integrate it such gateway with ERPNext. We need it for our e-commerce site. We have been able to integrate credit card gateway, but debit card is not done.

FYI. In our country each type has separate gateway managed by 2 different companies. Any help would be greatly appreciated.
