you really should have a lintel over the window,to put the bricks on,the window itself will not hold them up on its own,and they need to be tied in to the existing brickwork,it seems to me you do not know really how to do it properly,get a builder in,it will save you in the long run.
No, as NTG says, you need to use a lintel to span the gap. A lintel will be the depth of the double-skin whole wall, the window is only about 100mm deep.
if the window is upstairs and there is only a couple of courses of bricks above it then reinforced concrete lintels would be o.k. , but if it is downstairs and has a whole wall of bricks above it then you would need to cosult a builders merchant with the amount of courses and whether the roof joists are mainly supported on this wall. I had the same problem and was astounded by the calculation of weight above the window. also, although planning permission may not be needed, building regulations will, so you ae supposed to inform your planning office first.
sorry its all bad news

It strikes me, from your question, that you aren't very experienced in this field so I'm guessing that what you did was replace an existing window. If this is the case then the gap above the window is probably small. Even so, placing weight on top of any window frame is not a good idea. Have you considered using a piece of wood , cut to fit then covered with aluminum facia material? It should match the window nicely and could be furred as needed for thickness.
If, on the other hand, you have already cut a new hole in your wall and installed a window in it, You have already run afoul of at least a few regulatory agencies and would be well advised to cover the what is left of the hole ( and your butt) as soon as possible.
