If you want to provide a Graphic user Interface on a script, Tk is an excellent tool; it's most commonly used with Tcl but can also be applied to Perl (Perl/Tk) and Python (Tkinter). This example is a board drawing from our Tcl/Tk course illustrating the design of a multi-level GUI. A top level frame has three further frames packed into it, and into each of those we have packed widgets to complete the design of the display. The use of options such as "expand", "fill" and "sticky" control how widgets are enlarged to fill the available cell space, and how the cells themselves are expanded if a window is resized or given a specific size larger than it really needs to be.
