The idea of this approach is that you use the resource string to define 
the simple stuff and then do the rest in code. For example, define a 
list box but no elements, than add them in the initializer. Because the 
Resource is used as a base class for the class you are declaring, you 
can call its initializer from the derived classes initializer, and then 
make any changes that are desired (including adding custom widgets or 
even doing fancy things with sizers).
One of the main things that would need to be addressed is how sizers and 
layout could be defined using this approach
