[PD] Newbie request

Dude I sent you this info already ... its called pywinauto, a Python
automation suite for controlling Windows apps. You can send key and
mouse events such as opening a file dialog, "typing in the filename",
and hitting enter. There are plenty of straightforward info in the
documentation.
I paired that with the aforementioned ixi software's simpleOSC library.
There are examples around.
Once again. if you want a specific example, download the zip on this
page of my website where I use PD to send and receive control signals to
Python/pywinauto over OSC to control FLStudio.
I know you a "newb" and all, but that dosen't mean you can't get your
hands dirty and learn a bit. When I first put that all together I did
not understand OSC and had never used Python or automation software
before.
