After getting frustrated with deploying tutorial http://doc.trolltech.com/4.4/deployment-windows.html .
I tried many things to deploy and I found one solution and I reached to a conclusion.
I want the suggestions of the expert Qt people , Am I right?

Deployment Solution:-
Using the qt crater I build the example addressbook in release mode.
Then i browsed the exmple folder/release and copied the exe from there to a new folder.
Then i copied mingwm10.dll and libgcc_s_dw2-1.dll to the same folder.
This is working fine and i am able to run the program on any PC just by transferring the folder.

My question is that - Is it reliable method of deployment.Is it efficient in terms of execution speed?

Conclusion:

As i am able to deploy the application by above method, now I think we need not even to open command promt for namke, configure like things if we have installed the complete qt development envirnment.
Only those people need to follow the steps of the tutorial ( http://doc.trolltech.com/4.4/deployment-windows.html ), who use qt as a library.
Am i right?
