Unless your (clearly stated) GUI application has provision for being driven by command line switches--unfortunately, very few do--then you would need to use Win32::GuiTest to fill in the edit fields and press the buttons.

If, as seems likely, you are new to doing this, then be warned, it isn't easy to get right. And it's not something anyone can easily do for you or help you with unless they have a copy of gui application in question. You'll need to read and re-read the documentation for that module and expect to go through a considerable amount of trial and error before you get it right.
