The problem is that you're using one too many colons.  For line 574, try
something like:

    windowid = [Window newContent:&myRect style:myStyle backing:NX_BUFFERED
	buttonMask:NX_ALLBUTTONS defer:YES];

For line 575, it's:

    [windowid makeKeyAndOrderFront:self];

If you look at the specs for the Window class, this method requires an
unused but required argument to conform to the target/action paradigm.

Line 576 is fine syntactically.  The compiler complains because you haven't
declared the prototype method by including <appkit/ScrollView.h>.  For each
class that you use, make sure you include the header file for that class.
Hope this helps.
