I have been toying with an idea for an app since last Sunday. I am targeting a pretty big market, but on different platforms like:

1. Facebook app users

2. Nokia app users

3. Android app users

4. Blackberry app users

5. iPhone app users

I am based out of India and the above list is ordered by the size of the target market. (approx)

I work as a consultant on Databases and Business Intelligence. I work 9 hours * 5 days per week. My technical skills include SQL, Unix, Linux, Mainframe and a little of C and C++ (from college days). I have absolutely no idea about how to program these apps or what are the platforms/languages required.

Where should I start?

1. Should I learn the languages and start programming myself?

2. Should I pitch this to VCs? If so, since I am targetting the Indian market, which is the platform which I can use to pitch this idea? Without any technical know-how, how much effective it will be for a VC to hear the idea from me?

These questions have been itching me for the past few days and I hope HN can point me in the right direction.
