Yes.

It depends.  The askpass program doesn't have to be graphical, it
just needs to be able to access the password in some way.  It is
even possible to hard-code the password into a script that gets
created on the fly, but this means storing the password in plain-text
somewhere on the file system which is problematic.

That is probably the simplest approach.
