Is it possible to make two progress windows in maya?

it sure is... (The $d is just a delay so you can see it working!)

string $window = `window`;
    columnLayout;
    string $progressControlX = `progressBar -maxValue 50 -width 300 -ann "x prog"`;
    string $progressControlY = `progressBar -maxValue 50 -width 300 -ann "y prog"`;
showWindow $window;


for ($x=0; $x<=50; $x++)
  {
  progressBar -edit -progress $x $progressControlX;
  for ($y=0; $y<=50; $y++)
      {
      progressBar -edit -progress $y $progressControlY;
      for ($d=0; $d<100000; $d++)
          {
          }
      }
  }
