file = Dialog_Pickfile(/Write, File='suggestedFilename.txt')
IF file EQ "" THEN RETURN
OpenW, lun, file, /Get_Lun
... etc.

dialog_pickfile does nothing else than returning a string which contains
a filename, including the path. That string can then be passed as an
argument to openr, openw and any other function / procedure which does
something with a file.
Anyway, you don't write to a directory, you write to a file. And to
specify the file in IDL, you use a text string. The text string can
include an absolute path, or a path relative to the current working
directory (which you can find out by doing
IDL> cd, current=current_dir & print, current_dir
).
