Even though everything went correctly I cannot get display on beagleboneblack target board. I followed the Derek molloy instructions to make it work but cant get display. Can anyone help me asap.??

First of all, put code-tags around your code. It makes it better readable.

I'm not familiar with BeagleBone Black, but your main.cpp seems strange to me. To my knowledge it should be more like this:

@#include <QApplication>
#include <QPushButton>

int main(int argv, char **args)
{
QApplication app(argv, args);

QPushButton *btn = new QPushButton("Hello World");
btn.show(); 

return app.exec();

}@
