I've never run more than 10 km — is a half possible?

Yes. The plan starts from your current volume and builds the long run up bit by bit. With ten to twelve weeks ahead of you, a first half marathon is a reasonable goal.

No. You enter your key numbers by hand in two minutes, and you can log a completed workout in a few seconds. If you have a watch, your runs come in automatically.
