The easiest way to create a makefile for Qt is to use the qmake build tool supplied with Qt. If you have saved Qt1.cpp in its otherwise empty directory, all you need to do is:

qmake -project
qmake
make

The first command tells qmake to create a project file (a .pro file). The second tells it to create a platform-specific makefile based on the project file. The third executes the makefile.

#include <QApplication>
#include <QWidget>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QWidget window;

    window.resize(250, 150);
    window.setWindowTitle("Simple example");
    window.show();

    return app.exec();
}
