Qwt installation for Qt Creator on windows 7

Question

I installed Qt Creator. I would like to use Qwt. I downloaded and unzipped to "C:\qwt-6.1.0" folder. I performed the following instructions:

qmake qwt.pro
mingw32-make
mingw32-make install

There is no error. Everything is fine. But I don't know how I can integrate with Qt creator. I would like to use Qt via form editor. How can I install plugin?

Thanks

Platform
Windows 7

Versions
Qt Creator 2.7.2
Qt 5.1.0(32 bit)
