Calling “text link” widgets manually

I should clarify – not a “text link” – but a text widget. I’m using all nine and would like to use them to add custom subnav to each “page” of the site via http://codex.wordpress.org/Conditional_Tags#Variable_Sidebar_Content
I’m creating this for a client so I want them to be able to update those whenever they want so I’m hoping I can hard code text widget into those areas.
