Scott,

	As Marcus mentioned, you need to do this by way of the window
manager. The simplest way is to give a -name parameter on the command
line. To do it from within your program, you have to set the WM_NAME
property on the window. I think you do this via the xlib function: 

     XChangeProperty(display, w, property, type, format, mode,
     data, nelements)
           Display *display;
           Window w;
           Atom property, type;
           int format;
           int mode;
           unsigned char *data;
           int nelements;

Where property is: 
Xatom.h:#define XA_WM_NAME ((Atom) 39)

See the XGetWindowProperty man page for details.
