​Remember that Leo is itself a Qt application. The following works:
from leo.core.leoQt import QtWidgets
# Using the leoQt module allows
# the code to work on Qt 4 or 5.
app = g.app.gui.qtApp
# The already running Leo application.
w = QtWidgets.QWidget()
w.resize(250, 150)
w.move(300, 300)
w.setWindowTitle('Simple')
w.show()
g.app.my_widgets = [w]
# Save a reference to w so it won't be
# garbage collected at the end of the script.
# sys.exit(app.exec_())
# This would kill Leo.
HTH.
