Same reason most people prefer point-and-click games to text adventures. With text it's not obvious what to write next. With a GUI, you can roam around clicking on things until you spot something that looks sensible - it's like Lego. Additionally, you don't have to worry about making typos and not discovering them until compile time.

Code is only a means to an end. If you can achieve the result you want without it, then it's just an obstruction.
