newbie question: should I learn TKinter or skip it and learn more advanced toolkit?

[Porky Pig Jr]

I'm in a process of digging into Python, and one of the problems I'm
having is whether I should spend any time at all learning TKinter or
skip it and start with more advanced staff like wx or QT.

I have no experience with GUI whatsoever, so anything will be a
learning experience for me. The reason I've decided to post this
question is that I see some contradictory information in different
resources.

In 'Programming Python', learning TKinter is recommended -- before you
move to more advanced toolkits. The rationale is (i) it is built-in
and since it is also shared by TCL and Perl, it is well-maintained and
always in sync with the latest version of Python, (ii) it is fairly
simple to learn, small learning curve, easier to grasp some concepts
before moving to more comprehensive production quality toolkit such as
QT.

In some other resources TKinter is critisized as not well integrated
at Python at all, so recommendation is 'not to waste your time and
start learning GUI with either wx or QT'.

My intent is *not* to become professional GUI developer, but simply to
get a handle on it, so if I write some utilities, I can provide some
nice GUI if required. Yet of course, since I'm learning something new,
it would be nice to learn it 'right from the start'.

So: should I spend some time or TKinter or simply skip it and start
learning GUI with something like wx or QT?

(my background: solid C, enough C++ to understand the OOP concepts,
Perl, too much of it to my liking, BTW)

TIA.
