If I was to write something like this, I'd take a layout panel (Grid, Stackpanel, WrapPanel, or custom control based on Panel) and bind it to an ObservableCollection. Then you can have a template that displays using a Template Selector and basically show the user control that matches up with the type of the object in your collection. Use views and viewmodels etc. MVVM.
Hope that's not too vauge.
