The vocabulary here is "window size" (which includes the decorations) 
and "client region" (which does not).  Yes, when you specify a size, 
that includes the decorations.  You want to specify the size of the 
client region, which you can't do, directly.

Although it is possible to compute the size of each of the decorations, 
it is a tedious process, because of the possibility of themes.  All the 
edges can vary, so you end up fetching a whole bunch of system 
preferences values.  The easiest solution is to fetch your assigned 
window size and your assigned client size, compute the difference, and 
adjust yourself accordingly.  For example, try adding the following 
after you create the wx.Frame:

        ws = self.GetSize()
        cs = self.GetClientSize()
        # Bump the window size by the delta between the two.
        ws.IncBy( *(ws-cs) )
        self.SetSize( ws )
