Shopping cart with 'buy now' html buttons

Hi,

Is there a way to strip down opencart so it is just a very basic payment portal, and use 'buy now' buttons directly in my website?

I am looking for a robust backend for a ticket purchase system that will process a Paypoint/Secpay Merchant account and generate purchase reports.

I want there to be as few steps as possible involved - click the button on the site, enter name and payment details in one simple window, and that's it.

I don't need the whole 'shopfront' - is there a way out of it?

Thank you

Sarah

Maybe it would be worth looking at a different system, such as Romancart or Mal's ecommerce? Or Jcart. Just a thought.
