Creating a calendar without reinventing the wheel

I want to have a calendar in my app where I can create events. It would, or course, probably be stupid for me to write my own calendar from scratch. I want to leverage existing tools.

It seems to me that Google Calendar API would probably be a good choice. What I want to do initially is just get a "Hello, World!" calendar going: I just want to embed a calendar in a web page. Ultimately, I want to be able to change the behavior of the calendar. For example, when you click on any certain day, I want it to take the user to a certain form as opposed to showing them a pop-up.

There is a lot of material in the Google Calendar API docs and I don't really know where to start. Nothing I've seen looks quite like what I want, which seems weird to me because this seems like a pretty common need.开发者_如何学C

Is someone who has done this sort of thing before able to point me in the right direction?

My needs ended up changing enough that creating my own calendar from scratch makes sense. The calendar I use won't end up looking much like Google Calendar.
