Chicken is an esoteric programming language by Torbjörn Söderstedt, in which "chicken" is the only valid symbol.
A chicken program consists of the tokens "chicken", " " and "\n". Every line has a number of chickens separated by spaces. The number of chickens corresponds to an opcode. Trailing newlines are significant, as an empty line will produce a "0" opcode.
I wonder if it has any GTK+ bindings?
