I am answering my own post with a solution for mwm, in case it helps
someone else! (My window manager is not mwm so I need to keep looking
for a solution):

Here are directions from an EXCELLENT post on how to remove the
MAXIMIZE and MINIMIZE butttons from an mwm titlebar:

Configuring the Window Manager Decorations
-----------------------------------------------------------------
Firstly, the window manager decorations are controlled through the
XmNmwmDecorations resource of the shell. This is a mask formed by
combining
the following values:

#include

MWM_DECOR_ALL
MWM_DECOR_BORDER
MWM_DECOR_MINIMIZE
MWM_DECOR_MAXIMIZE
MWM_DECOR_TITLE
MWM_DECOR_MENU
MWM_DECOR_RESIZEH

For example, to remove the maximize and minimize buttons, the following
code
will do the trick:

extern Widget shell;

XtVaSetValues (shell,
XmNmwmDecorations,
MWM_DECOR_ALL | MWM_DECOR_MAXIMIZE | MWM_DECOR_MINIMIZE,
NULL);

Configuring the Window Manager Menu
--------------------------------------------------------
Secondly, the contents of the menu is controlled through the
XmNmwmFunctions
resource of the shell. This is also a mask, formed from the following
values:

#include

MWM_FUNC_ALL
MWM_FUNC_RESIZE
MWM_FUNC_MOVE
MWM_FUNC_MINIMIZE
MWM_FUNC_MAXIMIZE
MWM_FUNC_CLOSE

For example, the following code removes the Close option from the menu:

extern Widget shell;

XtVaSetValues (shell,
XmNmwmFunctions,
MWM_FUNC_ALL | MWM_FUNC_CLOSE,
NULL);

Note that in the specified question requirements, you probably also
want to
remove the menu maximize/minimize options for consistency, otherwise
the
user can still maximize/minimize the application using the menu
options,
even though you have removed the window manager decoration buttons. The
following code also removes the maximize, minimize menu entries:

extern Widget shell;

XtVaSetValues (shell,
XmNmwmFunctions,
MWM_FUNC_ALL | MWM_FUNC_CLOSE |
MWM_FUNC_MAXIMIZE | MWM_FUNC_MINIMIZE,
NULL);

If you are using Xt or Motif, look at resource XtNmwmDecorations on the
shell widget.

Some non-Motif WMs do honor the Motif hints. KDE3 does (though not
KDE2). Which WM are you using?
