There is a general rule to development, namely, anything you want to develop, you need to research it properly.
For example, I can design regular windows desktop applications because I know the languages to use, and have studied regular windows app very thoroughly.
If you wish to develop your own programming language, you can. But the questions are:
1. Why will you want to do that?
2. Have you studied existing programming languages well enough so that you can design something BETTER.
That is a recursive question, a programming language is used to create programming languages.
Even languages like Python, C can be used to create programming languages.
