Currently, no.

What *could* be done would be to use, in the non-Qt code, the GLib wrappers for gettext():

        https://developer.gnome.org/glib/stable/glib-I18N.html

(GLib itself requires gettext() to be present, so, if you're building Wireshark, you have the gettext() API available 
and you have any tools needed to process  .po files).  Then we'd create .po files for various languages; Transifex can, 
as far as I know, handle .po files.

(This won't internationalize the results of dissection; that could, in principle, be done the same way, but it would be 
a *HUGE* task.)

Note that we would not be internationalizing the names of the preferences, just the descriptions.  The preference 
*names* can be used in shell scripts, e.g. running TShark - or Wireshark! - from the command line with the -o 
command-line flag, so those shouldn't be internationalized.  They only appear in the GUI in the "Advanced" tab of the 
preferences.  (The same would apply to field names, as opposed to field descriptions, as they appear in packet-matching 
expressions, such as display filters and coloring rules.)
