What you ask for is possible, but is very complex, and much depends on the nature of the Perl script you are running. How can you tell what the progress is on your script? Does the script print out the percent done? There are Notebook tabbed widgets, progressbar widgets, and IPC modules that you can use, and you can google for many examples previously posted. But first you need to learn something about running Tk, see perltk tutorial and another tutorial . You can also read the good book, the bible of Tk, Mastering Perl/Tk.

It all seems overwhelming at first, but it all starts with writing a "Hello World" program.
