Answer 1

see through plastic

Answer 2

If you are using an acrylic base, you could try a gel medium.  "Golden" makes excellent gel mediums by the tub.  They are white when wet and dry clear with a very plastic consistency.  They come in light (puddle like) to heavy bodied (thick and hold brush strokes and peaks) gel.  They also come in a matte or gloss sheen.  I would try a medium bodied gloss gel and smooth it (depending on how thick you'd like the glass) onto an actual glass surface.  Be careful of air bubbles.  Let it dry completely until clear.  peel off gel (like a fruit roll) and cut it to size the window in your piece.  Put flatest side up and adhere to painting with super glue.  I say super glue because you don't need much and it would be the least noticable.  You can paint over this gel with acrylic or oil if you'd like

If this is an oil based painting, I would just bite the bullet and paint it to look like glass.  Unfortunately you can't put acrylic over oil because the oil never dries completely.  If you were to do the process above, I'm afraid that the gel will cloud.....however, that might be a great effect.  

Hope this helps

To put glass in the window, you either need to add slight distortions - which are uncommon in today's large sheets of glass but very common in older glass or individual panes mounted in mullions - which you would also have to paint,

  or you would have to add reflections - either glints of light from behind the viewer reducing the visibility of the glass or a light ghost of a scene like a door frame, etc., in the room.  Either of these might be done with a light glaze of a bit of white.

  I realize this may be a bit awkward, but why not find a piece of clean glass in a window and observe your painting in its current state to see the difference the glass makes, then try altering the painting to put the differences on the painting.
