Ask HN: What languages?

Hi

I've had a project up on the net for a while, and because I'm not a coder, progress has been out of my hands. For many reasons, I want to change this and either assist my partner or just plain take over due to current progress rate.

The project is an online press release aggregator and I'd like to find out what languages/databases I'd need to learn to carry on myself, and where I can find good tuts as well as compilers (for mac) for this?

Thanks
