I don't want to make a coin personally. I'll get others to do the techie stuff. (I do website programming, marketing, business end stuff).
But from my research, and my project, it would be of great great benefit to create a token off the back of bitcoin as opposed to Ethereum. Thus, my question and also if anyone knows of a sidechain to the bitcoin that permits this.
I'd say that your research, and by association, project, are flawed.
1. If you do "website programming", then you'd know javascript, and therefore be easily acquainted with Solidity.
2. Ethereum has a very solid platform to run tokens off of (they're called tokens, not coins, fwiw).
3. Many ICOs accept bitcoin for tokens using a dapp to process the purchase.
4. Exchanging BTC for ETH is easy. Really no use for excluding one for another.
All that said, maybe you're looking for
