Enter this grammar into ANTLRWorks. Notes: replace $$ by EOF in the first rule; the character is used in ANTLR strings so youll need to use the escape sequence for it as a token; you can treat a number as well as an identifier as an atom. Be sure to follow ANTLR convention about tokens vs non-terminals.
