Thanks for the feedback, but I think I need to clarify further...

I have next to zero experience with OOP and zippo with any GUI development (my only software development has been in the CLI). I've got to be able to walk before I can run!

I have multiple Python books that I started to read, but the one I listed in my original post is so far the easiest for me to get started with.

@f(x), thank you for the links, but the very first line about the book is "Dive Into Python is a Python book for experienced programmers.". The other links are well beyond my current skills.

As a introduction learning exercise of a GUI development, is Tcl/tk really that flawed?
Yes, of course I want to move on to using Qt as that's my end goal. I already have several utilities I want to create to run on my future N900.

Regarding my original question, it sounds like a resounding NO to attempting to install Tcl/tk onto a N810, correct?

@Capt'n: That makes perfect sense. Can you point me in the right direction to read more?

Cheers!
