QT 4 Toolkit Installation Guide

[Salazaar]

I have the installation file named:
qt-win-opensource-4.2.3-mingw.exe
but I don't think it really matters, does it?
Regards
p.s. my computer is after formating so I got lost in installation, I've been doing it about half a year ago

So install it and you'll get a start menu item, amongst a few others:

Qt by Trolltech vM.N.P (OpenSource)\Qt 4.2.3 Command Prompt

Just launch the Qt Command Prompt and you'll see how it sets environment variables. You will be able to use qmake and other tools shipped with Qt and you'll be able to launch applications linked against Qt.
