Building a QT client

So I designed my own altcoin (based on the tutorial by the user: "Shakezula" Whom I would like to thank because I have wanted my own altcoin for a while.) Me and my friends where going to use it amongst ourselves for like gambling and stuff... We are interesting kids. So I built the client and me and my friends have been sort of spreading it around our school for other people to use and stuff but there is a problem. While most of my friends are fairly technologically inclined which allows them to adapt easily to the command line client but people have been coming to me asking if there was something easier. I tried to build the QT client on windows but I continuously get errors from the "qmake" command. While installing I also get this error: "There is a problem with your MinGW installation: The installer could not find a valid C:\MingW\include\w32.api.h (Only versions with W32API 3.13 are supported) Do you still want to continue? (Your installation may not work.)"

I have a feeling that this is the reason why it will not build.

The errors I get are: "The directory name is invalid. Could not find qmake configuration fileRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized." While using qmake (coinname)-qt.pro and:
"bitcoingui.cpp:(.text+0x1d19): undefined reference to 'ZdlPv'" Along with others the same as that.

It will not build correctly. (or at all.) How may I fix this?
