Trouble with writing this (this is not the cash register)

Question

someone please help me with this i want to make it so that if someone crashes then he will get back up on mouse click
is there a way to do this

i dont think i have that gui thing or whatever, how
can i get itGUI is Graphical User Interface--buttons, windows, etc. Some programs have one, some don't. If you want your program to respond to mouse clicks, you have to use classes that are used for handling GUIs. (Note: I don't think your program would necessarily have to display any windows or other graphical elements just to be able to respond to clicks, but then I don't do GUIs, so I might be talkin' outta my butt.)
Here are some GUI tutorials. I'm too lazy to strip out the now-broken url tags, so you'll have to copy and paste the URLs yourself.
