You may want to take a look at the Tk::Stderr module.

Tk::Stderr

DESCRIPTION

This module captures that standard error of a program and redirects it to a read only text widget, which doesn't appear until necessary. When it does appear, the user can close it; it'll appear again when there is more output.
