This are probably NOT the same files as the ones you passed to the compiler:
According to the error-message, the type "string" in Window.cpp:17 starts
with a capital letter -- in your Window.cpp that's not the case.
The same is true for Windows.cpp:25.
If those are really the correct files, I would suspect that in one of
the Header-files included in Window.cpp and NOT included in Window.h
(that is: Graph.h or GUI.h or files included into these two) you
redefine the type "string" (to be equivalent to a type "String") -- so
"string" in Window.cpp refers to a different type as "string" in
Window.h...
If you remove the "using std::string;" in Window.h and replace all
occurences of "string" by "std::string", it should compile...
