I intend to push TIP #213 along as for Tk 8.6 now. I've added an
implementation for a native font chooser for windows and a scripted
dialog for everyone else that is based upon dkf's font selection dialog
but rewritten to use ttk widgets.
A patch against the Tk 8.6 HEAD is at
http://sourceforge.net/support/tracker.php?aid=1477426

I want to make one change to the tip. The current api says:

~ "-updatefont

~    This specifies the name of a font created with font create which
~  will be updated to reflect the details of the users selection; if this
~  option is specified, it provides the result of tk_chooseFont if the
~  dialog is not cancelled. Where the dialog implementation supports it,
~  the font will also be updated during the selection process. This
~  allows the effects of changing the font to be reflected immediately in
~  other Tk widgets."

Now both dkf's dialog and the critcl-based native implementations I have
for tkchat (windows and Gtk) use '-apply command' which is more flexible
and really more in keeping with the rest of Tk. If a named font needs to
be updated then it can be done in the apply script. The command has the
font specification appended as the final argument so we can have:
~  tk_chooseFont -apply {.textwidget configure -font}
or write a procedure to update any named font or whatever.

So I propose:
~ "-apply command

~ Specify a Tcl command to be invoked if the dialog's apply button is
pressed. The command will have the currently selected font description
appended as a list of (family ?size? ?style? ?style ...?)"

The API given now (-initialfont, -parent, -title, -apply) is sufficient
on Windows and for use with the Gtk font selection dialog. I do not know
if this is acceptable on MacOSX/Aqua and await comments. However my
opinion is that this is better than nothing and will in fact satisfy 90%
of users.

Provision of a single command (tk_chooseFont) and such a simple API
should help to make it simple to provide other font selection dialog
implementations where this will help to achieve a native look&feel (Gtk
and Qt being the obvious candidates).

I intend to push for voting as soon as possible.
