A short example:
h = uicontrol('Style', 'PuchButton', 'String', 'Stop', ...
'Callback', 'delete(gcbo)');
while ishandle(h)
disp(datestr(now, 0));
pause(0.25);
end

On one hand: no, you can create the button anywhere and use any method to obtain the handle. On the other hand: simply try it - when you do not have problems, it works.

Have the while-loop check if a togglebutton uicontrol has been pushed (i.e. what is it's value). If it has the loop will end
while(get(handles.togglebutton,'value')); %handles.togglebutton is handle to button
do_stuff;
drawnow; %force event queue update
end
