Note that Tkinter windows under the standard Python interpreter are
only 'alive' when the intepreter prompt is active. If you invoke a
function that takes a long time, the window will be unresponsive since
the Tk events are only handled within the Python interpreter loop. In
this respect IPython should have an advantage with threading.

I think the problem is that, by and large, almost all uses of GUIs are
centered on their being standalone applications and thus little thought
is given to having a command line coexisting with the GUI. Our needs
are pretty atypical in this regard.
