Perhaps something like the attached? It's not that fancy - it doesn't show a "preview" of the file or anything, but it will deduce the number of columns, whether there's a branch descriptor in the beginning or not. The actual reading is done by TTree::ReadFile.

Run as

	Root> .L ImportGui.C+ 
	Root> test1()
	Root> test2()

Check the code for more information.
