Creating glass and window frame

First we started creating glass by creating a object similar to a wall

Then opened material editor added some glossiness and reduced opacity to about 30 and changed colour of object to bright blue and applied that texture to object

And now for window frame we created two boxes and puted smaller box inside bigger box like this.

Then selected the object that will be the frame and changed standard primitives to compound objects on the right above all objects that you can create then pressed boolean  and pick operand and then just pressed on object and this is what happend

This is frame with glass inside and wood texture applyed
