This is the problem.
You doesn't need to do that. Your 1st and second step was fine. So now your steps shall be.
1. "QMake -poject" (To generate .pro file)
2. "QMake" (To generate make files)
3. "nmake" (To build the project with Microsoft compiler)

When i do the third step i get this
'nmake' is not recognized as an internal or external command,
operable program or batch file.

And i just installed the Qt framework , don't have visual studio

'nmake' is not recognized as an internal or external command,

This is because, it cannot find the compiler on your machine.

And i just installed the Qt framework , don't have visual studio

I assume, you used binary installer for that.
In order to get your application running, you must have an IDE.
Use QtCreator.

i have installed Qtcreator also but still get the problem

Please use Creator tutorial and docs.
