I've made a pull request for 4, 5, and 6.  I didn't remove the tk constants as it seemed you'd like to do all the files in one project for that.

Also, in query.Query, I noticed that all the widgets were created first and then they were all added to the grid last.  I didn't move any existing lines for this, but can do that if it's preferred.  It also seemed like helper functions might make it more readable (create_py_section, create_idle_section), but maybe that's too much churn compared to what this will end up looking like.
