I can imagine such a thing; it's called a programming language. A GUI application, you say? Well then you're just asking for a graphical programming language, and as they say, now you have two problems...
I think the more general-purpose a tool is, the more intelligence and/or general knowledge is needed to wield it:
"Here's a widget thromper. You push the big green button and it thromps the widgets."
vs
"Here's a car. It will get you from virtually anywhere to anywhere else. Don't kill anyone."
vs
"Here's a general purpose computer. Knock yourself out."
Ok, we need you to work on the music for this TV show. Your first job will of course be to build your composition suite from scratch so you can access our incredibly complicated database oriented file storage system.
If you're competent with your language, you don't always need to build a special purpose tool with it to do work - you can use it directly. You picked an example where a) libraries are lacking (high level audio manipulation) and b) good special purpose tools exist, but it's entirely possible to find tasks for which these things aren't true. The whole idea of shell scripts as a basic tool, or IPython/Jupyter as a reasonable interface to a variety of tasks, is based on this concept.
In my last "proper" job, I wrote a lot of code, and the vast majority was one-off; virtually none of it ended up in what you might call an "application".
