1. Minecraft.getInstance().displayScreen()

2. I don't think there are such thing, for most of the people a working web browser and this nice as forum is enough.

 

Your "free software" would be other people mods, possibly those who are working correctly, unfortunately you need to understand yourself what their code does. Anyway i think you will find this tutorial useful: https://github.com/TheGreyGhost/MinecraftByExample/tree/1-15-2-working/src/main/java/minecraftbyexample/mbe32_inventory_item

it doesn't have to be free, free is just preferable

What we meant is that there is no software (free or not) that will teach you how to make mods for minecraft. You will have to learn it by yourself by:

1) exploring vanilla code

2) exploring other people code, and that includes all the tutorials or example mods you can find around

3) try to write your own code and understand why it works/doesn't works. Sometimes it will be a process of trial and error

4) when all of the above fails to lead you to succesful results, asking for an answer on this forum the way to go

It doesn't look like you know Java, go learn that before trying to make a mod.
