Windows Distribution automation script (alpha)

Currently I am creating an automation script for creating Windows Binary
distribution, everyting is okay, but still cannot find out how to build binary executable via
commandline interface (not using easypaint.pro project file). If some one could
teach me how to do that, I'll make sure to provide Windows binary
distribution ASAP.
Maybe something as simple as this:

    cd ./EasyPaint/sources
    lrelease easypaint.pro
    qmake
    make
    make install

but for Windows instead of Linux.
