plain listbox/combobox?

FWIW, it takes about 2 seconds for the sub to run for me, plus a few more (I guesstimate 4) for Tk to actually draw it

OTOH, wxPerl pops up an equal amount of widgets in 1 sec, and it takes 1 sec to destroy them all

Both take up about the same amount of RAM

Its fairly similar to Tk (snippet of code generated by wxglade)

Distribution is easy with http://www.citrusperl.com//http://www.cavapackager.com/ for many platforms

There is even my wxWidgets / wxPerl / wxGlade tutorial
