Tcl/Tk, and Tkinter for all pre-installed Pythons but 2.3, have been included with every OS X since they started pre-installing 2.5. Here's a brand new laptop that I've done nothing to but run the 10.10.4 update and other recommended updates from the App Store app:
Python 2.6.9 (unknown, Sep 9 2014, 15:05:12)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.391)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>> root = Tkinter.Tk()
That works, and pops up an empty root window.
And it works with all python.org installs for 10.6 or later, all Homebrew default installs, standard source builds... Just about anything besides MacPorts (which seems to want to build Tkinter against its own Tcl/Tk instead of Apple's)
Also, why do you think Qt would be less of a problem? Apple has at various times bundled Qt into OS X and/or Xcode, but not consistently, and even when it's there it's often set up in a way that you can't use it, and of course Apple has never include PyQt or PySide. So, if pip used Qt, a user would have to go to qt.io, register an account, figure out what they need to download and install, figure out how to make it install system-wide instead of per-user, and then repeat for PySide against each copy of Python they want to use. Either that, or pip would have to include its own complete copy of Qt and PySide.
