Is there any way to display an independent variable which itself is not a part of any tvb in the protocol tree?
Look in doc/README.developer for the functions that start with  
proto_tree_add_ other than proto_tree_add_item().  If you don't need  
it to be filterable, you can use proto_tree_add_text() to add any text  
you wish.
It's also good practice to mark the variable as "generated" (meaning: 
not from the TVB) using PROTO_ITEM_SET_GENERATED()
