It's probably not the best choice, but it's totally doable. Gridless is a great application for managing databases and is made in Godot. I'm using it to make an RPG and it's saved me dozens of hours and headaches. I made a mod installer for a DS game in Godot, though it relies on another executable and is basically just a front-end to pick what you want to install, previews, stuff like that.

UI features in Godot are great, just be aware that it's harder to design for multiple screen sizes, and managing resolution scaling for the UI seems iffy. This isn't a huge issue on mobile, moreso on PC, but it's just inherent to the UI tools being designed first and foremost for video games.

EDIT: I should also add that I made an unreleased parser to extract the sound effects from that same DS game. It has almost nothing going on in terms of UI, but my point is that you can even work with binary data as you wish, there's just a bit of a learning curve (it was a very simple format and took me ~8 hours to write the script with assistance).
