What are some GUI that allow me to cut sections from a video without re-encode? To illustrate: Say I want to delete the 10-11 minute point of a 20 minute video and create the new video of 19 minutes without re-encode. Same as described in the link below; think: removing commercials from a tv show.

https://superuser.com/questions/681885/how-can-i-remove-multiple-segments-from-a-video-using-ffmpeg

I was trying to do the above with ffmpeg, but without re-encoding. I currently can do it by using each command separately i.e.:
    ffmpeg -ss 00:00:00 -i input -to 00:00:00 -c copy output 
And then I'd concaticate the pieces I want together.

I looked up how to find the nearest i frame to try and get more accuracy when choosing times. But putting all this together and checking the video after getting each piece of information...turned into a very inefficient process.

So I wanted to know if there are any gui (video editors) that support this functionality of ffmpeg in a more manageable manner. I mean the simplest and ideal process I can think of is: I toss the videos in the editor, i click an option to disable re-encoding, i choose the sections I want. Then it just chooses the nearest i frame to my cut choices (if it displayed the i frame that would be good too) and does all the above stuff.
I don't have much experience with the modern capabilities of video editors. The ones I have used have very limited functionality when it comes to rewrapping/'no-encoding' compared to ffmpeg command prompt, or just always re-encode to begin with. So I'm just curious if there are editors that have the kind of re-wrapping functionality that ffmpeg command prompt has. Otherwise I'll need to pursue the solution from a scripting perspective, of which I know nothing about.
LosslessCut is an open-source video cutting tool. Its interface is built using Electron, and its backend is ffmpeg. It's available on the three main operating systems (Linux/Mac/Windows), and also from the Mac, Microsoft and Snap stores.
