[Gambas-user] Title Bar colour when minimised or change icon

[KKing]

Is it possible to change the colour of the title bar when it is 
minimised on the task bar?
And or change the icon?
I want to use as  health indicator, if all good have either the title 
bar or an icon being a shade of green and be able to change to amber or 
red depending on level of issues.
Possible or should I investigate a tray icon approach?
