I think that what you mean is that you'd like to delete the text in the
window rather than the window itself. If the text widget is called txt, then
you can do 

tkdelete(txt, "0.0", "end")

If the top-level Tk window is named top, then, after creating the window,
e.g., tkwm.geometry(tt, "-100+100") will position it 100 pixels 100 pixels
from the right top corner of the display.

More generally, I found it useful to read Welch, Jones, and Hobbs, Practical
Programming in Tcl and Tk, to learn these kinds of things.

I hope this helps,
