Ulfilas, or Wulfila, made his own alphabet for the translation, the letters drawing heavily from Greek and Roman. The photograph above comes from Robert Pfeffer's very excellent site (in German and English), which has historical information as well as mythological art. In this Youtube video, Pfeffer does an absolutely fascinating job pronouncing a passage from the Gospel of Luke:
What amazes me how un-Germanic it sounds, at least at first, but then you pick up on certain words that look similar to words in modern German or English. (Incidentally, I left a comment in German on the video, or at least I tried.) Though we can't be sure what the language really sounded like, to me this is as convincing as it gets.
Take a look also at this lesson from Alexander Arguelles's excellent YouTube series on modern and extinct languages:
As you listen to his translation of the text above, you'll see some connections. Let me give one more example of Gothic - the Our Father, in this case using Roman characters and a thorn (þ) for the th sound:
Atta unsar þu in himinam,Just looking at the first line, we see atta = father; unsar = unser (our in German); himinam = Himmel (heaven). The second line: weihnai = holy (so Fröhliche Weihnachten, which is Merry Christmas in German, literally means something akin to "Happy Holy Night"); namo = name; þein = thy, thine. Then a few lines down, daga = day.
weihnai namo þein,
quimai þiudinassus þeins,
wairþai wilja þeins,
swe in himina jah ana airþai.
hlaif unsarana þana sinteinan gib uns himma daga,
jah aflet uns þatei skulans sijaima,
swaswe jah weis afletam þaim skulam unsaraim,
jah ni briggais uns in fraistubnjai,
ak lausei uns af þamma ubilin. Amen.
And so on. What we'll likely not fully know is what these people did for fun, what they ate, what music or art they might have created, what their society was like. But the idea that a Germanic culture existed down near the Mediterranean region back in the 4th Century, and that they spoke a language related to ours, however distantly, shows us a significant link in a long chain that extends even farther back to places we can only imagine.
P.S.: Robert pointed a a great series by BenJamin P. Johnson, "Gothic for Goths." The first video begins with the alphabet:
