Don't know about a Textfield, but if you chose to go with a RichEdit, you 
can use the sub Win32::GUI::AdHoc::richEditScroll, available at:

http://www.bahnhof.se/~johanl/perl/Win32GUI/

I guess you still have to keep track of the selection and at what line it 
is located somehow.


Just looked up the Textfield thing BTW:

An application sends an EM_LINESCROLL message to scroll the text vertically 
or horizontally in a multiline edit control.

EM_LINESCROLL
wParam = (WPARAM) cxScroll; // characters to scroll horizontally
lParam = (LPARAM) cyScroll; // lines to scroll vertically
