Create a Bitcoin / VIX / GOLD index

I would like two indexes: 1. that calculates the Bitcoin divided by VIX (Volatility Index) and 2. BTC / (VIX * GOLD). This should be implemented by using an API preferrably or a web scraper. I need the values to be calculated at specified intervals per day and stored in a MySQL server. Perl or PHP programming language preferred for deployment, but if you use other language you are good at, let's talk.
