C, F and G (and etc) chords, are the same 'chords' (at least in
name) regardless of instrument.
If you have a guitar chord cheat sheet, which I am sure you can find online, or else search for whatever chords you need and you can find the pictograms and fingerings, you can then use the "Daily Ukulele" books as they are, with the
existing chord names, but instead of playing the songs on uke, you play them on guitar, piano, etc.
Also, IIRC, the standard notation shown for the treble clef, with the lyrics, in those books is for the
melody line for the vocals, and not indicative of any
specific instrument.
Unless you are looking for different songs than what are in those books, if you already have those books, they can still be used for any other instrument that is not in fact a ukulele. This way you can save yourself some money.
