QT 3 (linux) to 4(windows XP)

Dear all

I have developed front end based on QT 3.3.4 ( LINUX PLATFORM and C CODE)
I need to develop the same for windows (XP).
I started with QT ver 4 for windows( MINGW 32) and tried to self learning a lot.
I am able to convert the form ( which was developed on QT 3.3.4 ( LINUX PLATFORM and C CODE)) to the new format . But after that there is a problem.
I made a folder and put the new form in it.Then I made a main.cpp file.
Used the commands qmake -project , qmake . Got ui_formname.h file .
But when I make it I get stuck.
I need to know

Doesn't QT for windows version 4 has this C ++ project approach as it is in QT 3.3.4 ( LINUX PLATFORM )
Since there one needs to just make the form and write own functions for the slots and the thing runs well.
In QT ver 4 for windows the only option is to make form ( DIALOG ,Application etc)
I tried commands qt 3 to 4 also

In fact if I am able to convert the form ( which was developed on QT 3.3.4 ( LINUX PLATFORM ) and make windows exe somehow I can try and add my private slots .

Somebody guide please.

Thanks in advance
