I don't know from your post the exact size of your window, but there are some very important safety issues to be considered.
Number one is your inexperience in the handling of large pieces of glass. This requires the use of suction cups w/handles and some knowledge of how the glass itself is going to react to different stimuli such as binding, pinching, etc.
The last thing you want is a large pane of glass breaking into two or three large jagged pieces while you are holding it 6 inches from your body. This could be fatal in extreme cases.
Another thing working against you is the awkward position you will undoubtedly have to be in to get at the glass. This will most likely require two people, putting them both at risk.
While installing a fully-framed window is a fairly simple and relatively safe job, the handling of large, unframed glass is very dangerous and not to be taken lightly.
I know it looks like an easy job (just a few screws, right?) but, I think this is one area where you would probably be best served by paying the professional to do what he knows best.
