If the wing uses a standard type foil and you have that foil, create a planar, set it facing left or right at centerline of the aircraft. Size the planar the length of the root chord.
Apply your foil texture to it filling the length of the planar, therefore the length of the root chord.
In either left or right view, create a box with as many segments as necessary to structure the wing curvature. Convert the box to editable poly, then move each row of vertices until you have the box shaped per the wing foil.
Just one more of many ways to do the job. :-)

Once done, repeat for the wing tip foil.
