Looking for a simple token sale webpage that will accept payment in Bitcoin. The design is mostly done so just need the backend that accepts payment in Bitcoin and issues the token(s) to the user's Ethereum address.

Currently the user is promoted for the following information via a web form:
Bitcoin address you will send from:
Ethereum address where you would like to receive your tokens:
Amount in Bitcoin you wish to buy:
Email Address:

I believe the best way to do this is an AJAX call upon form submission that will insert the values into a table and generate a new bitcoin address to accept payment, which will then be displayed to the user. Then a script should run periodically in the background that checks all previously unpaid transaction, and when payment has been confirmed should send the tokens to their Ethereum wallet.

I am open to suggestions on better ways to accomplish this.

Below are the database fields I had in mind:
btc_address_from (the users bitcoin address)
btc_address_to (this is the new address that should be generated, where the user is told to send payment)
eth_address (ethereum wallet where tokens will be sent)
amount_input (amount of BTC the user said they planned to send, this might not even be necessary since we will use what they actually send anyway, but I'll keep it as a backup to check any problems with payments )
amount_paid (amount of BTC actually paid)
email_address
ref (refferal ID, that can just be a URL paramater if it exists, ?ref=XX, and passed along as an invisible field in the form)
btc_paid (datetime)
token_sent (datetime)
