if I understand it right you should think of a code editor in old delphi or 
sybase power++ or netbeans: the form editor generates some source code and 
the user can only change code between the generated parts.

As a solution a would propose to inherit the editor widget and overwrite the 
keypress handler - if the cursor is located in the readonly area, any key 
except cursor movements should be discarded... of cource this concept can be 
extended by setting grey color these area, change cursor icon and so on.
