No, no, ugh!  There are much easier ways to do this.  There is a
TkTable widget which does most of this for you.  If you do not want
any C-language extensions, there are many ways to wrap
widget-name-to-x-y-coordinate mappings and you can make nice little
procedures which do it for you.

I made some little procedures for creating per-window variables, for example,
so each toplevel can have a sort of "namespace" associated with it.  (This
was for a former employee, so I can't give out the code, unfortunately.)

You can do similar things for tabular data.
