The window is 9 feet long and 6 feet wide, so the total area of the window is 9 * 6 = <<9*6=54>>54 square feet.
Since each small glass square has sides that are 1 foot long, each square has an area of 1 * 1 = <<1*1=1>>1 square foot.
To find the number of small glass squares needed to make the window, we divide the total area of the window by the area of each small square: 54 / 1 = <<54/1=54>>54.
Therefore, 54 small glass squares are needed to make the window.
Each glass square costs $2. How much will the window cost?

If each small glass square costs $2 and we need 54 squares to make the window, then the total cost of the window will be 2 * 54 = $<<2*54=108>>108.
Therefore, the window will cost $108.
