There are some additional resources you might consider using, and will
likely get faster responses with regards to Qt questions.  First is the
PyQt5 mailing list.
https://www.riverbankcomputing.com/mailman/listinfo/pyqt .  Also there
are the normal Qt forums: https://forum.qt.io/

As to your question, you can add a label to a window the same way you
would add the label in the first place.  Likely you'll want a QBoxLayout
widget to place the label(s) into, with the addWidget() method.  Take a
look at the Qt docs for signal, methods, etc.
https://doc.qt.io/qt-5/qboxlayout.html .  For the most part, PyQt5's
method calls, signals, and slots, are the same in Python as they are in C++.
