First of all the images you posted you cant make anything out what you got there. Secondly you should contact a local Architect when doing something like this, not only for structural reasons, but window design as well. He will layout window detail based on the window sizes available from a certain manufacturer or you can take his drawings which indicate opening detail to a place who sells windows, and they have catalogs of window combinations and sizes to make it work with what you have.

Brass Hinges or Heavy Quality Stainless Steel.... But Only Use 3 Peice of Hinge sand not 4 Peice... Because that will not look good unless the door thickness is more than 2 Inches

Hello Rahul, You can get this design done either on solid wood carved by cnc or you can use veneer on flush door and with skilled workmanship you will achieve this design. For the golden circle design you should use polished brass profile as paint is not a very pragmatic option due to its short life and finish might look bit tacky.
