My understanding: Yes, you must have an App Engine application, and you
must run appcfg.py update_queues to create the App Engine Task Queues
before you can use them.
If you do not have an App Engine application, you should probably be using
Google Pub/Sub instead. It is many times faster and more scalable, as well
as supporting more sophisticated use cases. I work on an application that
makes heavy use of App Engine Task Queues, and while they are pretty good,
they have some interesting limitations that Pub/Sub solves.
Hope that helps,
Evan
