Bitcoin Payment System Question - Wordpress/PHP/HTML Expert Advice Needed

[bluebit25]

I'm interested in setting up a bitcoin payment system where a buyer comes to a website to purchase a digital download. Once he adds the item to the shopping cart and clicks the "Pay with Bitcoin" button he immediately get's a QR code where he has to send his bitcoins.

My Question: What program or code do I need to check if the payment has been sent to a bitcoin address, and afterwards sends them a download link automatically?

Wordpress is not needed

Yes, like a processor. But without a middleman or service like Bitpay. I did some digging and found this: http://bitfreak.info/?page=tools&t=bitsci

Basically having the ability to process transactions within a website and without a service like Bitpay, the business can offer products cheaper than their competitors that use a service that requires fees.
