What literature to read to create a convenient and customizable analogue of android studio in python?

Question

Python

There is a kivy (python) framework on which you can create cross-platform applications. But there is no normal graphical environment for it, I mean the one that is in android studio or visual studio, godot engine, etc. Where you can add a button or text from the palette (a list of UI elements - widgets are called in Kivy), change the size of the button with the mouse, etc.
There is a desire to try to implement something similar.
The main components will be:
- a tree of widgets (buttons, labels, checkboxes, etc.)
here you can select widgets for subsequent actions with them, change the order and depth of nesting, delete, etc.
- a palette of widgets (from here you can add widgets)
- application preview area (here you see the result; two modes - in normal mode, you can click on buttons, enter text, etc.; in edit mode, you can change the size of widget elements and their position, while you cannot click on buttons)
- inspector (there are a lot of sliders, knobs, checkboxes that correspond to the values ​​of the parameters of the currently selected widget).
- text editor (here you can see the final text and edit it).
There will also be an undo system, a system of shortcuts (when you can assign keyboard shortcuts to certain actions).
And perhaps even a virtual assistant bot in customization, which, for example, will collect statistics of called actions / actions, analyze them, for example, for the frequent use of certain sequences of actions and offer to create a macro from them or put an action in the form of a button or checkboxes on the toolbar or in the context menu right mouse button.
What can be read on this topic?

Answer 1

Write plugins for any of the IDEs, for example Google PyCharm plugin development

Answer 2

This is a very large area, entire companies are engaged in this, and even then they are not doing well.
By the way, all this is button-throwing

- widget tree (buttons, labels, checkboxes, etc.)
here you can select widgets for subsequent actions with them, change the order and nesting depth, delete, etc.
- widget palette (from here you can add widgets)
- application preview area (here you see the result; two modes - in normal mode, you can click on buttons, enter text, etc; in edit mode, you can change the size of widget elements, their position, while you cannot click on buttons)
- inspector (here are a lot of sliders, twists, checkboxes, which match the parameter values ​​of the currently selected widget).

Real developers don't. Most of my colleagues (and me too) do not use this garbage.
