Polish the interface of applications

[Xiao-Qin Xia]

Hi, everybody,

When I run my applications based on Tkinter, there is always a TK icon at
the left of the title line of the window (northerwest of window), is there
any way to replace it with my own icon (.bmp, jpg or gif)?
The other thing is when the application (main.py) is running under windows
XX, there is always a DOS window opened besides my application window. Is
there any way to avoid displaying the DOS window?

Cheers,
