Is there any guidance for making a mod like you said? I only got some books and online tutorials talking about manipulating recipes, blocks and armor.

I need to launch the game without showing main menu for simplicity. Now I know how to connect to a (remote) server and join its running world directly (without showing main menu) by passing --server and --port command args to launch the game. It works pretty well. But I have no idea on how to create a single player world or reenter the single player world created before directly without main menu. I really need this functionality. Please help me. Many thanks in advance.

Thanks for reply. I intended to support mods so I guess forge is needed. As for versions, I plan to support from 1.6 up to 1.10. I thought lower version could be easier.

I want to make my own custom launcher for minecraft, where player selects single player mode or multiplayer mode inside launcher instead of game main menu. When player launches minecraft, it goes directly into game world without showing the main menu. I am new to minecraft development, but I have experience with java programming. I don't know where to begin with. Is there a tutorial about buiding custom launcher? If I want to launch minecraft with parameters like server and port, how could I launch it, which jar file to launch? Many thanks in advance.
