ariels response sums up most the options when it comes to Tk Geometry management. To see all of the options check out the main documentation for Tk (perldoc Tk from your command-line on most platforms) and check the section called "Tk Geometry Management".

In my experience Tk::grid and Tk::Table are the easiest to use and best documented. Tk::Table has the advantage over grid in some circumstances because it is already in a scrolled frame (actually it ISA scrolled frame :) ). That may or may not be of use to you.

Good luck,
