I've attached an image of something similar to what I want (the GUI).
I'll just try to explain how I want this to work:
1. I create folder were I put the application with the GUI (the one I want you to make)
2. I create a bat/cmd script in the same folder
3. Within the bat/cmd script I call the application with the GUI
4. When I then run the script, the output will show up in the GUI window
