I don't have much experience with Guile, but AFAIK both programs you mentioned are written in C, but support Guile in one way or another. GNU Make supports Guile as an embedded extension language [0] and WeeChat supports Guile as a scripting language for writing plugins [1]. There are a few other apps mentioned on the Guile website [2] and more on their Libraries page [3].
