Qt executable size problem : very big

Hi everyone, I've a 4.3 Qt application developped under Windows. I've ported it to Mac OS and it works fine, but I've an interrogation about the size of the executable whitch is 120 Mo . I don't know really why it is toooo big. I use many frameworks but it is the cause ? Does anyone have an idea about this and can tell me how to do to mimimize the size especially I must to put the exécutable to download by clients.
Best regards.

No, I've compiled on release mode and I've not linked to the frameworks and plugins.

120MB? It looks like you statically link to Qt in debug mode.
