The tree's node structure has to be such that it will hold a string rather than an integer. As C has very primitive string handling, you have to either

1) allocate enough space in each node for the maximum sized string you'll allow (this can waste much space), or

2) allocate a string (character) pointer in each node, and malloc() each string out of the heap space as you use it (if you're constantly freeing and reallocating strings due to changes, this can cause problems with eating up your address space through heap fragmentation).
