It's a Linux app called Buttons.
All it is, is a graphical window that you can create your own buttons in. Move them around, resize them, name them however you want. All the buttons do is run a bash command. You have checkbox options to keep the bash window open or hide it, or open another window when you click the button to set an input file, etc.
You can save the layout to a file and share it with friends, or load multiple layouts for multiple windows with buttons.
The only point of this program is to avoid actually opening a terminal window and typing anything in. Make it a button.
