Hi, I would like to start developing apps. I am quite familiar with html and web design, some php, mysql,css but would like to start making my own app. I would like to start on cascades.

I was just wondering if it is possible to write an app to share your calander with your friends? Would it be possible to access such data? If so, how would I do that structurely and is there any sample apps out there for such a thing? Would it be too complicated for a beginner like me?

Thanks in advance!
