Is it possible to use goto with switch?

Not quite but you can do this:

switch(color)
{
case GREEN:
case RED:
case BLUE:
     Paint();
     break;
case YELLOW:
     if(AlsoHasCriteriaX) {
         Paint();
         break; /* notice break here */
     }
default:
     Print("Ugly color, no paint.")
     break;
}

OR you could do this:

switch(color)
{
case GREEN:
case RED:
case BLUE:
     Paint();
     break;
case YELLOW:
     if(AlsoHasCriteriaX) {
         Paint();
         break; /* notice break here */
     }
     goto explicit_label;

case FUCHSIA:
     PokeEyesOut();
     break;

default:
explicit_label:
     Print("Ugly color, no paint.")
     break;
}

Ahmed's answer is good, but there's also:

switch(color)
case YELLOW:
    if(AlsoHasCriteriaX)
case GREEN:
case RED:
case BLUE:
        Paint();
    else
default:
        Print("Ugly color, no paint.");

people tend to forget how powerful switches are
