A do while loop is frequently used in menu's - which you should have, if you offer several possible options for the user to choose from.

Have fun!

If you are asking if this is a good plan, I would have to say not really. First don't use goto. This will make you program logic very difficult to follow and can lead to some hard to find bugs. However using functions is highly encouraged. I would also suggest you stop using the operating system specific functions and headers unless you actually need something contained in these headers. Since you seem to be using C++ there are better ways of keeping the console window open besides using _getch().
