QCoreApplication is for non-GUI programs. QApplication is for
QWidget-based programs.

Halfway between the two, there's also QGuiApplication (new in Qt 5)
which is for GUI programs that don't use QWidgets (e.g. Qt Quick or
OpenGL).

You can find the details in the Qt documentation, e.g.
http://qt-project.org/doc/qt-5/QApplication.html
