    now I'm arrived to step 5 but I think I have some problem, this is the ouput after lunch the command:

    configure.exe -debug-and-release -platform win32-g++ -qt-sql-mysql -l mysql -I C:\mysql\include -L C:\mysql\lib

    Creating qmake...
    mingw32-make: Nothing to be done for 'first'.
    Running configuration tests...
    g++: error: CreateProcess: No such file or directory
    mingw32-make: *** [arch.o] Error 1
    Could not find output file: No such file or directory
    WARNING: The DirectX SDK could not be detected:

      Either install the Direct X SDK or pass -opengl desktop to configure

          Just one question, do you only need to build the MySQL plugin ? If so, there's no need to rebuild Qt completely

            This is the first time for me with C++ and QT so for me it's all new and I do not know what are the requirements needed to achieve my goal.
            I want to make a windows application that keep some signal from a RFID antenna attached to notebook from serial and store data in a mysql database.
            To start I want only to connect to mysql database and read a table data.

            So I guess I need only mysql plugin.

              Then just compile the MySQL plugin like described in the documentation, no need to rebuild everything.

                  What does that message have to do with the current question ?

                              Each platform has it's own gotchas but the *nix variants are generally more easy to deal with when it comes to dependencies like MySQL

                              You're welcome :)
