Qt GUI application with a 3D Unreal Window

I would like to write an application similar to Unreal Editor, but using Qt as the GUI framework. So only the 3D panel where OpenGL or DirectX would normally go, would be an Unreal panel instead. Has anyone figured this out? I think the question has been asked before, but I can’t find any answers.


One of the only things I can think that’s similar is creating a plugin and expanding the editor.

I’ve created a GUI within C# Windows Form that can communicate with Unreal through a TCP Connection in runtime, if you want to modify things as the game is running.
