During the last days I converted an app. to support exactly what you
describe that you want to have it. It's not that easy. There is no
simple way only to change some ressource file (at least, I don't know
one). I used the following method:

1. Have all resources for all languages in a single res. script.
2. Prefix all their names with a language prefix (i.e. "E_" for english,
   "G_" for german etc.
3. At all places where the resources are called, wrap the resource name
   with a function which prefixes the parameter string with the current
   language prefix, i.e. change
       DialogBox("FileOpen", ...);  to
       DialogBox(LangRes("FileOpen"), ...);
   where LangRes is of type char * and returns a pointer to its argument
   prefixed with "E_" or "G_".
4. When you change the language, you must manually cause all resources
   to be reloaded. But usually you will not have any Dialog boxes open
   so you may only have to update Window titles etc. from Stringtable
   resources, or the change the Menu and Accelerator table.

This method may sound not very nice but it's fast. I don't know of
languages with other fonts than the standard ANSI set. But if you have
the needed fonts, you can at least specify them for Dialog Boxes in the
dialog editor.
