Let me see if I understood what you want:
1) click an object.
2) that objects shows a countdown (like, 3...2....1...)
3) when the countdown is finished, another object appears (i'm guessing some sort of "confirmation" pop-up)
4) when you click that second object, you change layout.
if that's the case, then it's super easy
1)Create your "button"; could be a sprite, a text or a button object. and create a variable called "countdown" on it, and set it to 4.
2)With the mouse or touch object use the condition "on object clicked/touched" (that object has to be your button) ---> set it to 3.
3)Then on another event make this: When object.coundown =or< 3, every 1 seconds, as long as it's greater than 0 ----> object: substract 1 from countdown.
4)And when object.countdown = 0; make the second object appear by setting it's position to where you want it to be. (originally have it placed outside the layout,)
5) and when that object is touched/clicked -----> go to desired layout.
In order to display a text over the first object, there are several ways; you could make the object with 5 sprites and set frame to timer. or you could place a text over it and set that text to object.timer.
Also, I really recommend you go trough the beginners tutorials as this is really basic and you should have learned it there. Then read the manual at least once, so in the future you know what to look for when in doubt.
