I'm a bit unclear as to exactly what you're looking for...
Is this a title that you want rendered no matter who installs it and on which server?
Do you want it on every page of your component?
If yes to either or both of the above & you wish to let the admin of your component add this title themselves then:
add a config parameter to your component's xml, for example, a field called
component_message. Then retrieve the value of the parameter as set by the admin of your component/site and echo it to the page. How to add parameters to your component:

On the other hand, if you want a 'fixed' message for every installation of your component that can't be overridden by the admin form the configuration, declare a helper function/variable in your helper.php file OR a JDom class and echo it on every layout.
Try looking at how the page title is already added to your views/layouts for more hints.
Hope it helps!
