Why do not I have Qt Gui Application option? - qt

As you can see from the picture it does not show Qt gui application option. What is that I am missing?
By the way it is Qt 5.2

It's the Qt Widgets Application that you are looking for. All Qt GUI applications use Widgets.

Can a Qt 5 project invoke a Qt 4 project?

I have built a UI application using Qt 5.7 and an independent widget using Qt 4.8. The widget uses QGIS API, which is incompatible with Qt5. Is there a way to run the widget from the Qt5 based application?
