My concertina is a G/C; will i be able to play in D easily?
Not quite as easy as C or G, initially, but certainly worth attempting.
Many players who wish to play "English" music in an "English" style (primarily melody on the right hand, chords etc. on the left hand) opt for a G/D instrument, since many tunes are in G, D or a combination of both. By choosing a C/G, you will learn how to play in D for those tunes which demand it, so will stretch your ability.
So; in my book, a good choice! Also; if you wish to play in an Irish style, then C/G is almost "standard issue".

PS - in terms of what you play, initially ..... if you learn "by ear", then I would suggest a tune, or song melody, which you already know. That way, you will only deal with the variable of learning it on a new instrument.
