Simple skeleton to create launcher with buttons from tuple of tuples `self.cmds_to_launch`: first element ('bla') is label text to display on button; second element ('some command') is actual command to run when corresponding button pressed. Note that `self.cmds_to_launch` may contain any amount of tuples, provide no scrolling though.
