I give here *complete* directions---you will write < 10 lines of code!  

Start Interface Builder, select New Application from the menu.  Get the  
Inspector panel from the Tools menu, first switching it to Project mode and  
clicking OK to create a project file (these will go in your home dir for  
now...sorry).  Next switch the Inspector to Class mode.  In the class browser  
window, select the View class (under Responder), Subclass it, and then Unparse  
the new class to generate code templates.  Go back to the Project Files  
Inspector, find MyView.[hm], and click the Open button.  The two files pop up  
for editing.  In MyView.h, add the line

    - drawSelf:(const NXRect *)rects :(int)rectCount;

just before the @end.  Saving that, add this to MyView.m just before the @end:

    #import <appkit/appkit.h>

    -drawSelf:(const NXRect *)rects :(int)rectCount
    {
        PSsetgray(0.); PSnewpath();
        PSmoveto(10.,10.); PSlineto(10.,10.); PSstroke();
        return self;
    }

Save this file too.  From the IB Palettes, drag-and-drop a CustomView into the  
"MyWindow" window (use the resize knobs to make the View fill the Window).  In  
the Attributes Inspector, choose its class to be "MyView" from the scrolling  
list.  Save As into "myapp.nib".  Select ".nib" in the Project Files inspector  
and click Add; double-click on myapp.nib in the pop-up browser to incorporate  
it.  Finally, choose Save All, and then Make, from the IB menu.  You will now  
have an Application in your home dir called myapp.debug.  Launch it.  Enjoy  
your "one point of light" :-)
