This is a simple indented list. You can simply enter the lines with various indentation as you have already done in your message. Or you can feed the date into one of the index making programs like makeindex or xindy. If you want some sort of graphical representation of a tree structure try pstricks.
For requirements like this plain TeX gives you more control and less hassle IMHO. Also look at eplain.tex as well as pstricks as handy addons to plain.
