[Qt-interest] Running windows application

[HardMaker]

  Hi,
I'm new in Qt world. I'm developping a little application in qt under 
windows with mingw32. Everything it's ok when run the application in Qt 
Creator or from a qt console. But when I try to run the application 
making double click, I recive a message from OS about missings dll.
I search the files, put all then in the application folder (mingwm10.dll 
too) but now, I have message's like "I can't find procedure entry  point 
... " QtCore4.dll
I think's the problem is mingw32, then, I try with Microsoft Visual C++ 
2008 precompiled version of Qt. All work ok, and the application just 
need 2 dll (qtcore4 and qtgui4)
Not happy with this, I try to do cross compiling from linux to generate 
the windows application. All work fine, but again, the application send 
a message "I can't find the procedure entry point..." qtcore4.dll when 
run under windows.
I test the application in other PC, with new instalations of windows, 
and not work sending the same message's.
Are some way to make a windows application, compiled with mingw32, run 
out of development enviroment using shared linking?
Very thank's all
