If you are using R2016a and the App Designer you can use

doc uilamp

to do this I would think. I haven't used the App Designer or its components yet myself though so I don't know what the limitations are on GUIs created that way are.

For dead-simple notification, just fill the BackgroundColor of your favorie ui object.

Try this as a template:

function toggleTest
% Make fig
figure('Visible','off',...
    'OuterPosition', [0 40 400 400],...
    'MenuBar', 'none',...
    'ToolBar', 'none');
hFig = gcf;
% A simple pushbutton
uicontrol(hFig,'Style','pushbutton',...
    'Units', 'norm',...
    'Position',[0.2 0.6 0.6 0.25],...
    'String','TOGGLE',...
    'Callback',@toggleColor);
% STATUS INDICATOR --------------------------
uipanel(gcf,'units','norm',...
    'Position',[0.2 0.2 0.6 0.25],...
    'BackgroundColor','g',...
    'tag', 'PANEL_TOGGLE')
% --------------------------------------------
% Save toggle state
data.TOGGLE_STATE = true;
% Pass Handles
data.Handles = guihandles(hFig);
% Save & Launch
guidata(hFig,data);
movegui(hFig,'center')
hFig.Visible = 'on';
end
function toggleColor(hObj,~)
h = guidata(hObj);
switch h.TOGGLE_STATE
    case true
        h.Handles.PANEL_TOGGLE.BackgroundColor = 'r';
    case false
        h.Handles.PANEL_TOGGLE.BackgroundColor = 'g';
end
h.TOGGLE_STATE = ~h.TOGGLE_STATE
guidata(hObj,h);
end
