Only wbar-config depends on GTK 2 and libglade2. I suppose we could simply remove this utility package because wbar is quite easy to configure just by editing some text files. However wbar has not seen any upstream releases in the past years and the rewrite to use evas instead of imlib2 was never finished. I don't use wbar anymore but it seems it is still useful for other people although there is at least one bug that triggers a segfault when the taskbar is activated. (#919108)
Otherwise it is perfectly usable. If there are no other major issues wbar should be part of Debian, but at one point in time we must reevaluate this statement.
