I can't understand!! All dlls the program need is with the .exe file!

You forgot to copy the QPSQL driver plugin to that other machine. Make sure it's in sqldrivers subdirectory and that you have copied all necessary DLLs to the same directory where your executable it.

Well guy, the files I'm sending for the "testers" are these:

Pasta de C:\caixa_xpress

dependency walker says that's no problem with the dlls here in my computer!!
but in tester's computer the "driver not loaded" message appears!

I forgot some file??
The QPSQL driver plugin you meant isnt qsqlpsql4.dll??

Create sqldrivers subdirectory in that directory and move qsqlpsql4.dll there.

No way!!

I did it and still with the same problem!!
We should think in computers that have never the QT libraries installed, this is the kind of computer the testers are using!!

In my computer it works well but in others no!

You can use Dependency Walker to check whether all DLLs are in place. Just point it to qsqlpsql4.dll and it should list all required DLLs that you should copy to C:\caixa_xpress (of course except the standard windows DLLs).
