You may begin from this:

$ cat showlog.py
import sys
from ScrolledText import ScrolledText

interval =50 # ms

def displayfile(f, textwidget):
    textwidget.insert('end', f.readline())
    textwidget.after(interval, displayfile, f, textwidget)

if __name__ == '__main__':
    st = ScrolledText()
    st.pack()
    displayfile(sys.stdin, st)
    st.mainloop()

$ python showlog.py < mylogfile.log

HTH,
