     "The package is a wrapper around Tkinter".  It runs Tkinter
in a separate thread and sends commands to it.

     That's a wrapper for the BLT package for Tcl.
(http://blt.sourceforge.net/).  The documentation
for the wrapper says it was developed for Windows 98.

     That outsources the job to Google, which could choose at any time
to cancel that service (as they did, for example, with their SOAP-based
search API.)

     "You acknowledge and agree that Google may stop (permanently or 
temporarily) providing the Services (or any features within the Services) to you 
or to users generally at Google’s sole discretion, without prior notice to you."

     Besides, outsourcing something this basic just adds something else
that can break.
