Chamomile help?

[Chinacatsunflower]

How hard is it to grow chamomile indoors?
How big does it get?
How large of a pot will i want to put it into?
How do you dry the harvested flowers?

and any other info would be excellent! I LOVE chamomile but for some reason it seems like it would be hard to grow indoors. If you can convince me it's not i'd really apreciate it!
