Well, if you're really starting from square one, just sitting down in front of the Qt SDK may be a bit too much to ask for.

You could certainly grab a couple of "intro to programming" books and work your way through them. But the best way to get a quick start, in my opinion, is to try out a few little examples in a language that doesn't require much effort to set up and get started.

I kind of like the idea of starting with "Javascript", because every web browser supports it, and you can see the results of your code instantly. And it does have variables, data types, functions, and most everything else you'll find standard in modern languages.

I haven't tried it myself, but there's a website called CodeAcademy that seems to offer an excellent introduction to languages like Javascript. There are lots of other Javascript resources on the net, and you can certainly just try out your own code by writing it to a text file and opening it into pretty much any web browser...

Anyway, just an idea.
