IMO you should decide whether your tutorial is only about Windows+MinGW or about Qt at all. Because at the beginning you say that anyone can use it and then you write everything assuming the user has Windows and MinGW as the compiler. If you want your tutorial to be for absolute beginners, you shouldn't assume they'll know how to "convert" your tutorial to fit their needs (for example a different path, a different compiler, etc.). Either cover all possibilities, focus on one combination or use such solutions, which fit all environments (for example don't write "use make", because with msvc you need to run "nmake" and not "make").
