Magento - How to send an email with a custom template?

Question

I've installed a gateway module which works through a site-wide based payment, I mean, the customer pay the order inside the store. I know all payment statuses for any transaction, for example, 0 = "Order received", 1 = "Checking payment", 2 = "Authorized" and others. I would like to send an email to the customer (with Bcc to store administrator) to notice that the payment hasn't been authorized. Can I create a custom email template from admin dashboard and send an email using that new custom template? I would like also to put a link on the message which allows the customer trying make a payment again.

Any lights??

Answer to the first question: It's not possible to do in admin panel only. In admin panel you can only translate already existing email templates.

Answer to the second question: dig into code, for example, take a look at the Mage_Sales_Model_Order::sendNewOrderEmail() method, and then come back if you have some concrete questions.

P. S. it's always a good idea to include "what have I already tried" section to your questions.
