Replacing broken passenger window

My passenger window broke and I'm replacing it. I got the door trim off but found out my window isn't made like most car windows. It has holes and there are three bolts that sandwich the glass. My question is how do I unsandwich the broken glass so I can sandwich the replacement glass and put it in the car? Do I need a special tool or something? I tried moving it with screwdrivers but it seems pretty stuck.
