Tk is SPECIFICALLY designed for TCL. Tkinter works ONLY by embedding a
TCL interpreter. You statements are misleading.

This is true. Lots of people lack the skill to create professional
quality GUI applications however lots of GUI devs lack the skill to
create clean and intuitive API's also. Tkinter/TclTk and WxPython
\WxWidgets has lots of warts in this respect.

Just because someone wants to entertain ideas for a new GUI does mean
they are starting flame wars. I would say out all the responses so far
YOURS is the most emotional.

True Tkinter does no Database, networking, threading, etc. However i
would not call an embedded TCl interpreter "lean and mean".

I will agree with Kevin here. Hey, he's not ALWAYS wrong you know;
just most of the time! ;-)

Tk's event binding (whist quite powerful) is also quite overwhelming
in the sheer number of event sequences alone and leads to spaghetti
code. See my recent thread about the subject.

I think it could happen much sooner if people got serious. However it
won't happen tomorrow for sure.

The old "reinvent the wheel" argument is only valid when wheels
already exists. Currently we have triangles (or maybe pentagons) but
