It uses the UI and works in ExtendScript Toolkit, but i have not yet tried it in an InDesign script:

// establish how much of the bar is filled = 0;

// build dialog window
var win = new Window("dialog{text:'progress bar',bounds:[100,100,240,180],\
      runBtn:Button{bounds:[20,50,120,70] , text:'Add 5%' },\
      progress:Progressbar{bounds:[20,10,121,20] , minvalue:0,maxvalue:100,value:" + i + "}\
   };"
);

// button to add 5% to the bar
win.runBtn.onClick = function() {

	// this will animate the bar to 80%
	while (i <= 80) { 	 win.progress.value = i; 	 i++; 	 $.sleep(10); 	}; 	// if (i <= 95) { // add 5% if the bar is less than 95% full i = i+5; i = parseInt(i); win.progress.value = i; } else { // reset bar to zero if you have reached 100% alert("You have reached 100%!"); i = 0; win.progress.value = i; }; };

// show user the dialog window
win.center();
win.show();
