I wrote a GUI application about a week ago in just a couple of days, under 200 lines of code including the GUI and backend logic. Since it's Python, it 'just works' in both Windows and Linux. Using the ttk widgets, the interface looks native wherever it's run.
Python's built-in IDE, IDLE, is written with tkinter. It's not feature-packed like the big name IDE's out there, but it works and looks decent enough nonetheless.
I wouldn't want to learn GUI programming with Tcl/Tk (again), but now that I have, it's quite easy to get what I want done with it and quickly.
