I'm actually making exactly what you're looking for: https://moo.do

It does to-do lists, calendar, and email all in one. The only caveat is it only supports Google Calendar and Gmail so far.

Let me know if this solves your problem or if there's anything I can do to make it better for you.

Not the GP and not quite what I'm looking for (I live in a terminal as much as possible, and on my phone as little ) ... However that looks like a kick-ass product. I hope it works out for you.
