creating a keyboard for a new locale

Hi Is there a straight forward way to create a keyboard for a new locale [dz-bt] for use in Linux GUI's like GNOME and KDE? If seen information on XIM http://www.suse.de/~mfabian/suse-cjk/xim.html and SCIM http://ns.turbolinux.com.cn/~suzhe/scim/index.html - but these look like they are designed principally for creating complex IME's for CJK languages - and overkill for what I need to do (have a keypress or shifted keypress generate a single Unicode character) - Chris cfynn@gmx.net -- CJ Fynn
