This is two, or possibly three, distinct unrelated questions as best
I can tell.
1a) Yes, anything you can do in an IDE you can do at the Python
interactive command line prompt. Or by running your script directly
in a terminal window. Personally I find it less hassle to do it that
way, since IDEs usually don't work the way I want them to.
1b) Python can be compiled down to binary if you try hard, with
utilities like Py2exe. You don't usually want to do that, though.
1c) ...because there are plenty of ways of wrapping up libraries
so that Python scripts can use them. ctypes (in the standard
library) is a good place to start.

Probably. It sounds like what you really want is a framework of
some sort that knows about things like "the timer event", and using
it from the interactive prompt won't be for the faint of heart!
Someone must have walked this path before, though.

The Python In Music wiki page (http://wiki.python.org/moin/PythonInMusic)
has an entire section on MIDI packages. I've never used any of them,
so I can't comment.
