How to ship Qt apps?

[Morea]

How do you ship Qt apps, ready to run on (almost) ANY windows computer? I've tried, but one person got a crash in qtcore.dll (I think it was).
How do you do this with only mingw?

My way of doing it is to use a Nullsoft installer script, which will bundle all the files you need into a self-extracting archive. There is a ready-made one here; you will need to change the name of the app, the version number and add or remove Qt libraries as needed.

I generated that script with the HM NIS Edit program, which is an editor for Nullsoft installer scripts. It comes with a wizard which you can use to generate a script exactly like that one.
