Emacs dynamically changes font size based on window width and column fill

I use Emacs on a small netbook to write code, and I set the font size so that the fill-column (79) characters fill the width of one "maximized" window (that is, a fairly large font size). However, if I open two windows side by side, I would like the font size in these windows to automatically decrease, so that each window width holds at least 79 characters.

Before I start to delve deeper into this (I don’t know how to use Lisp), is it possible to get the width of the window every time I resize it, divide it by placeholder columns and based on this result choose a monospace font size?
