You need to import plasmascript from PyKDE4 if you dont have you can check-out

You don't need KGlobal for now

And you need to use plasmascript.Applet not plasma.Applet

You don't need shape.. For now.

You should set a pen for your painter like;
 painter.setPen(Plasma.Theme.defaultTheme().color(Plasma.Theme.TextColor))

and before painting you need store current painter state with;
 painter.save()

and after drawing text with;
 painter.drawText(rect, Qt.AlignCenter, "Hi there")

you need to restore your painter state with;
 painter.restore()
