You chose the wrong forum. Start with Programming Beginners, learn programming, write some apps first; when you learn "where to put codes" you could start thinking about potentially maybe starting OS development.
Copypasting code from tutorial does not mean "completed".

Do you understand what the GDT is, and why you need it? If you do then it should be obvious that the code goes somewhere before you use the selectors defined in the table.
If you don't understand why you are setting up a GDT then you need to do more reading before you start coding.

"Many user apps" without a single link to such apps means you've written none and are still a newbie.

Put it in a file.
Where do you put all the "other codes"? (Note: there is no word "codes")

Can you elaborate on what you mean by where to put the code?
Control flow wise the GDT setup should be one of the first steps in the os boot.

It's completely possible that the apps aren't publicly available and can't be made available for whatever reason.

Without any specifics on what they do it's just a brag. I don't believe it.
