Keep in mind that the qt license is gpl and horde is lgpl and in order to use your app commercially you need to purchase a Qt license.

The very simple main.cpp

code=
<source lang="cpp" line="1">

#include <qapplication.h>

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

widget.show();

return app.exec();
}

Here is the custom pro file customized for ubuntu and my box you will need to modify this to your paths.
