I am assuming that you want to have this menu available to you within whatever desktop environment/window manager you are using now. Is that correct, or do you want the menu available in console?
One solution, which probably won't satisfy your wish to use your graphical skills but will give you menu items, is to use a window manager such as fluxbox or xfce. With those two, you could write the short scripts you want to run and put them into a bin directory in your home directory. Then modify the window manager's menu to add the names of those scripts.
Another option might be to use dialog, kdialog or gdialog. I have to admit, though, that I have not used any of those, so I can't be much help with constructing the menu you are looking for in them.
