I can imagine that Win32::GuiTest and/or Win32::ActAcc are useful for this. Maybe Win32::GUI as well.

You may have to call Win32 API functions using Win32::API, but probably the Win32::GUI::Text($hwind) sub is enough.

(I see now that some of these modules aren't up-to-date on CPAN, so google for more recent PPMs)
