How do you precicely position an object, for example, a text field in a window?

Tk is different than the W32 world...In W32, you draw your dialog box with a dialog editor. Unker Tk, almost everyone creates them it with code. I definitely recommend that you adapt your GUI to one of the different geometry managers, unless you REALLY need to do something unique. 90+% of the time, I use pack() and grid().

Remember, under Tk, everything can stretch. Break everthing up into related Frames...so they size appropriately.

Once you get used to it, you won't want a dialog editor. It took me a while to "get it", but now wouldn't use a dialog editor...
