actually this can be done, at least with X11; here with debian I can do
something like:

from tkinter import *
from subprocess import Popen

root=Tk()
f=Frame(root, container=1, width=300, height=300)
f.pack(fill='both', expand=1)
pipe = Popen(('urxvt', '-embed', str(f.winfo_id())))
root.mainloop()

Still, I am not so sure if this is a good idea.
First, those embedded windows can be tricky by themselves; there may also
be DE/WM dependent issues (no idea if this works on windows or OSX at
all).
Then you will have to consider user interactions with the terminal,
for example what if the user decides to simply type "exit" at the command
prompt? Or hits Ctrl+\ while the process is running?

Of course I do not know what you want to achieve in detail, but maybe if
you want to use a gui with tqdm it would be a better approach to catch
the string (I guess the "data" in your code snippet?) and instead of
printing it to stdout just putting it on a tkinter Label.
I don't know about tqdm, maybe you could change the output format a bit
to omit the progress bar at all, calculate the value for the
ttk.Progressbar with the percent value and put an output string like

47% 76442/161258.81970214844 [14:12<16:26, 86.00KB/s]

on a Label next to the progress bar. That would give the user all the
information they need, would be easier for you to handle, be more
reliable and surely make a better looking gui.

Best regards

Michael
