i have no pd here right now but using pyext this script should do it 
(untested):
save that script into the same dir as your patch and give it the name 
"filedialog.py"
make an object [pyext filedialog openpanel].
now you can send messages [dir /tmp( and [ext .wav( to set startpath and 
extension
and [open( to open the dialog...
let me know if it works.

import tkFileDialog
import pyext

class openpanel(pyext._class):
         _inlets=1
         _outlets=1

         def __init__(self):
                 self.dir = ''
                 self.ext = ''

         def dir_1(self, dir):
                 self.dir = dir

         def ext_1(self,ext):
                 self.ext = ext

         def open_1(self):
                 f = tkFileDialog.askopenfilename(initialdir = self.dir, 
defaultextension = self.ext)
                 self._outlet(1,f)
