Is there away where I can get Tk to represent this data in a directory like hierarchy structure, similar to Tk::DirTree. So I can have a display of folders representing the Business Units, then inside those folders another folders for Groups and then for functions?
Yes, just do what Tk::DirTree does (Tk::DirTree is pure perl, so Use The Source Luke).
Also, if I read the above data into a hash then can I use TList to do the job?
Sure, why not.

I run a Win32 PPM repository for perl 5.6.x and 5.8.x -- I take requests (README).
