Please do so.

Please provide more details here.
Probably you mean that you cound not link both perl/Tk and Tcl/tk into one
single binary file (either DLL or exe or somesuch)

Otherwise all is possible: Perl is able to contain both Tk and Tcl::Tk, and
they even could run together in one application.

Following lines are toy and nothing usefull, but application starts and even
works (buttons give their responces, and all is good until it gets not good
:):) 

use strict;
use Tk;
use Tcl::Tk;

if (fork) {
  tkinit-> Button(-text=>'text',-command=>sub {
    print STDERR "he-he, perl/Tk\n";
  })-> pack->MainLoop;
}
else {
  Tcl::Tk::tkinit-> Button(-text=>'text2',-command=>sub {
    print STDERR "he-he, Tcl::Tk\n";
  })-> pack->interp->MainLoop;
}

Also, two different loops are here; however "right" coexistence should rely
on one single MainLoop'

Of course your efforts on adding perl/Tk compatibility to Tcl::Tk would be
very appreciated. Please share your ideas, .

I, for one, not spending many efforts on improving perl/Tk compatibility
right now, because I realized that I can move entirely into Tcl::Tk module.

Best regards,
Vadim.
