[Gimp-user] Help newbie with plugin dev guidance

[MakerMatrix <forums gimpusers com>]

I've experience writing code in Perl, C, on UNIX platforms.  But new to GTK,
gimp plugins, python, and just about anything dev-related on Windows.

I want to write a plugin/app that does the following:

- Opens a GTK dialog that displays an MxN matrix of int values and a few buttons
to interact with those values.
- Reads data over serial from an Arduino sensor to populate that matrix with
measured values.
- Once fully populated, allow the user to send the MxN matrix to a GIMP plugin
that processes it into an M*S x N*S (where S > 1) 8-bit grayscale image that can
then be saved in a format that GIMP probably doesn't already support (that I
don't yet fully understand but do have access to code that reads/writes it).
- Run on Win/Mac/Linux if possible

If you can please point me to resources/tutorials for learning how to do
something like that, I would be grateful.  I've already watched 2-3 YT videos on
plugin development with script-fu and am about to go check out the tutorials
link that I saw when I registered on the site.
