That’s actually a really nice idea.
You can accomplish this with GIMP by removing all the UI panels (which it calls Dockable Dialogues) and tools from the toolbox, and then adding some of them back in. By default it starts off more complicated though, which I think is why a lot of people find it overwhelming to learn.
You’ve inspired me to do an experiment making a really simple and stripped back GIMP configuration. I can send you the config file if you want and you can let me now what you think.

I use Libreoffice for all of my business admin, from invoices to pricing models. It’s fantastic software.
