So you know those old computers that could only work if you used a floppy disk? I would like to make a version of that but with a better interface - so it can only run the programs I create and nothing else. I would make a virtual computer on my computer through programming, or use scratch or python but I'd like it to come on when I turn the computer on and stay on permanently (so no exit or minimize buttons etc). Does anyone know how to program this? reprogram a computer to do this? Or programmed a computer so that it only runs your program?

Building a computer has nothing to do with it. What you want is your own operating system. I suggest you go to google.com and search "msdos" and "4dos" and "drdos" and any other system you learn about to see how they did it. You can then write your own operating system to only run programs that contain codes identifying them as yours.
For example, early IBM computers would not use a floppy disc if it did not have the letters "IBM" in the boot sector.
Another example is any computer preloaded with Windows operating system. Microsoft requires the bios program to refuse to load any non-Microsoft system. In that case, building the computer does have something to do with it, because bios is wired into the mother board.
