I have recently completed the documentation for the Draw Comands and Input Commands.
So, yes nuclear offers some support in this direction to a certain point.
Here is an overview of the relevant functions.
Input - Function Overview
Integer InputHasMouseClick( id as Integer)
Integer InputHasMouseClickInRect( id as Integer, x as Float, y as Float, w as Float, h as Float)
Integer InputHasMouseClickDownInRect( id as Integer, x as Float, y as Float, w as Float, h as Float, down as Integer)
Integer InputIsMouseClickInRect( id as Integer, x as Float, y as Float, w as Float, h as Float)
Integer InputIsMouseClickDownInRect( id as Integer, x as Float, y as Float, w as Float, h as Float, down as Integer)
Integer InputAnyMouseClickInRect( x as Float, y as Float, w as Float, h as Float)

EDIT:
However, I would rather edit it in the AppGameKit surface than in a nuclear window.
But it would also work in a window.
I think the effort is similarly great.
