In theory you could do it, have a look at a recent thread on forms in the
mailing list archives:

I don't think so, beyond what is already present with the input and secret input
status codes, as well as just "being on a page".

Probably not, why not use another protocol? (again, see the linked thread)

Multiline input is theoretically possible by percent encoding a linefeed.

For file upload, maybe have a look at one of the adaptations mentioned in the
linked thread (Dioscuri, Titan, and Inimeg)?

Depends on what you would call an app. You can have a look at some pieces
published on the mailing list:
Tic Tac Toe (seems to be inoperable at the moment [1])
Interactive Fiction
