Oh yes.  Look into widget_list,/MULTIPLE along with
widget_info(wid,/LIST_SELECT).  Finding subdirectories in a platform independent
way is somewhat troublesome in IDL, and usually requires various
platform-specific flags to findfile() being employed.  If you don't care about
platform independence, your job will be easier.
