As others have eluded, I don't think there is an "easy way" to port the code over. You'll have to basically start re-writing things and solve problems as they come up. Having written things in both MFC and Qt, you may end up doing a lot of re-design since the frameworks can vary quite a bit with some things. If you're looking for something that may be easier to port so that it works in other platforms (i.e.Linux), WxWidgets may be an easier port.
