How to embed a standalone text editor like Notepad++ into QT application

[Niagarer]

Hi,
I think it is not possible to embed it like a widget really inside my program, but at least as a new opening window.
So that I can click a button in my application, a new standalone text editor-window (like Atom or Notepad++) opens, I type in some code, click on a button again, the editor window closes and my application got everything, I typed in.
Because I can't write such a good text editor myself and it would not make sence, while there are many good text editors out there.
Is this possible?
Thanks for answers!

@Niagarer You can't embed external applications like Notepad++ as widget into your app.
