Running shell script in separate window

[Don Dudley <ddudley mybearcreek com>]

I have an app with several functions that call bash or kshell scripts. 
The scripts produce output, which I want to show in a separate window
created by my application, then close it when the script finishes.  Is
there a way to start a terminal window from my app, or do I somehow
redirect output to a gtk window?

Thanks,
Don
