Python 2.5 get text string dialog box

Research from trying to figure out how to write something in python 2.5 to create a dialog box for inputting a text string that I can then parse. Shouldn't be too hard you'd think. But, I don't seem to have access to any Tk libraries and am pretty sure that installing them isn't an option in my environment. So far I have a lot of stubby leads and no answers. What I've tried so far:

Things would be so easy if I could just use wxPython:

Python 2.5 has a built-in text entry prompt called raw_input() (changed to just input() in python 3). The problem is that running it in the GSEOS python console gets me an error "EOFError: EOF when reading a line". The best that I've been able to figure out is that if my python is configured a certain way, raw_input will open a console window for the new input, or something like that, but I don't know how to get there. Apparently a text file can be piped into raw_input(), which doesn't help me but is interesting. In my case, I won't be running python in what is normally entitled a "python window" anyhow, I really want a pop-up dialog box.

This thread had a fascinating example where the win32console functions were directly manipulated, there must be some clues in that, but I couldn't import win32console in my python.

I also learned that ctypes() can be used to access the windows win32dll which has basic prompt boxes accessible, very nice but I can't seem to find a text input dialog, just various OK/Cancel boxes.
