Produce a plain page with only a message

Question

I am integrating a payment gateway into a distributed wordpress plugin. The notification page (page that the gateway sends info to after the payment has been made) requires only a message of "success" or "fail" to be printed. In that page, I need access to the database and some org options. Can someone please tell me how to produce such a page (i.e. no menu, no header, no footer and etc.)? The gateway in question is alipay.

See http://codex.wordpress.org/Pages#Creating_Your_Own_Page_Templates

Just don't include get_header(), get_siderbar(), get_footer().
