Is this something that can be corrected via a configuration file (e.g. qtrc)?  If not, can somebody point me to where in in the source code tree I should be looking and what I would need to do to correct this?

Widget appearances are dictated by the style code, which is applied by QT3.  You would 
have to either fix QT3 or create a new widget style to make everything correctly HiDPI-sensitive.  
However, you *may* be able to improve your experience somewhat by selecting the "High 
Contrast" style and turning on "Use wider lines" in its configuration.  This will make most widgets 
somewhat larger.  It isn't the most elegant style, though.

If you are interested in authoring your own widget style (requires C++ knowledge, 
unfortunately), you can find existing styles in tdelibs/tdestyles and tdeartwork/styles.

If you want to patch QT3 directly, my guess is that you would have to look at
qt3/src/styles/qcommonstyle.cpp , which has a lot of size-related magic constants
you could play with.
