Its not uncommon but often it can be simplified by using classes.
In particular the classes can expose an interface that makes the 
structures appear simpler by providing the access mechanisms 
needed so that the outer code is ignorant of the structural complexity.

Not for an arbitrarily complex structure such as you have defined. 
You will need to write your own I fear.
