Well this will depend on your skill level, the menu will be easy if you have edited others before. (making the map show through is a simple edit, like 2 lines)
HUD scripts are as simple as a window script. (i didn't know if you where making one of those as well)
All the windows seem like they are not editing a great amount of the default scripts just a matter of changing the positions and such.
the options menu will be challenging the first time, i would look at Juan's Option Menu. It shows a lot of good examples of how to do that and a few others.
as long as you have a basic understanding of scripts can read and remember things then you should be fine (with a few mistakes along the way)
