Which widget should I use?

Hi list!

I need to represent some data in my application. The data is actually a
trace of functions. The size of the list is not fixed, but it has a limit of
200 elements. When the 200 limit is reached, I clear the older element and
then add the new one.
I have the list in a file (from procfs) and now I need to show it. I thought
about to draw the name of the function inside a rectangle and then an arrow
pointing to the next element. Something like this:

_____            _____
|func1|   --->   |func2|
----------           --------

But I don't know what kind of widget I need to use. Maybe this is not the
best way to represent this... should I use a treeview to show the list?
Which are the advantages?

Thanks in advance.
