First part of the task, yes.

Second is to have the block of left aligned labels centered around the
middle of the longest string.

The buttons are in a table from the start. The problem was to have
different spacing because of the string length change. Imagine some very
short strings, then the label are all shifted to the left side. This is
looking "irregular" on a screen filling dialog.

But since I'm using GTK+ 1.2 and cannot switch to 2.x this was somewhat
difficult to solve. For now I'm using a predefined spacer label with
enough spaces in it for each set of strings.

A better solution would be welcome although...

Thank you,
