this depends on what kind of functionality you want our of your button. Does it have to act as the rest of GUI module, or is this stand-alone?

GUI.CreatePicture doesn't respond to clicks, but if you overlay the picture over your grey button, the latter might still trigger.

If you have just one button, Mouse.Where is simpler than having to deal with the GUI module.

lets say i have a .jpg image that i want to be my button, how would i code that?
currently im using something like this:
i still want the button to perform a process though

Turing:
import GUI


procedure hello
locate(1,1)
put "Hello User, you have clicked Button #1!"
end hello

procedure hi
locate(1,1)
put "Hello User, you have clicked Button #2!!"
end hi

var button1:int:=GUI.CreateButton(25,25,0,"Button 1",hello)
var button2:int:=GUI.CreateButton(25,50,0,"button 2",hi)

loop
exit when GUI.ProcessEvent
end loop

instead of the exit when GUI.ProcessEvent loop, you have one with Mouse.Where that checks if the mouse has been clicked and it's located over your image. If the conditions are met, you call the procedure.

If you want to have two buttons, you would need two such if statements.

The GUI module does all of that, and abstracts it away from your view, but as a result it is very inflexible.
