I have written a simple text-entry widget application based on my
MGH_GUI_Base class. You can get it, along with the rest of my public IDL
library at

http://katipo.niwa.cri.nz/~hadfield/gust/software/idl/

The text-entry class itself is called MGH_GUI_SetText. Here is code that you
would use to create an MGH_GUI_SetText object in blocking mode and get data
from it when it exits:

    odlg = obj_new('MGH_GUI_SetText', /BLOCK)

    odlg->Manage

    odlg->GetProperty, STATUS=status, VALUE=value

    case status of
        0: print, 'Cancelled'
        1: begin
            print, 'Widget returned', value
        end
    endcase
