Basically, male betta's are solitary fish and do best on their own. A lot of people see them and think "ah, you look so lonely!" so they put some fish with the betta, but in reality this will just severly stress the betta out. Betta's are territorial fish and become stressed when other fish are made to occupy their space (a lot of fish also have no concept of territory, and so often swim into the betta's personal space unknowingly and either get terrorised by the betta or vice versa). Male betta's are basically happiest on their own.
Female betta's can be kept together in all-female groups (although never mix male and female), but it is not nesarsary to keep them in such groups.
Betta's are agressive, territorial and slow moving fish. In community tanks, they either attack other fish (particularly bright, small colourful ones like guppys), or get attacked themselves (they are often too slow to out-swim other fish when they are picked on) and find difficulty in competing for food with other fish since they are slow and not very competetive eaters.
With goldfish, there are many types of goldfish, and each type has its own ideal habitat preferances. Comet and common goldfish enjoy temps near freezing and love nothing more than a nice cool pond to live in, while other types of goldfish like bubble eye or ryukin goldfish prefer more sub tropical temps and like a cool, but not cold, large tank set up to live in.
Most slim goldfish will easily live in freezing water conditions, while most fancy goldfish will die in them- its mostly due to the fact that the majority of fancy goldfish we know and love today were bred in tanks indoors, and so prefer a warmer set up, while most of the larger growing slim goldfish were bred outdoors and so prefer to live outdoors too.
Also needless to say, fancy goldfish need at least a 20gal to live in, while slim goldfish like comets, shubunkins and common goldfish do better in tanks 75gals+, or ideally a suitable large pond.
On a side note, if you put a goldfish with a betta the goldfish would also probably eat it or kill it sooner or later as goldfish will eat pretty much any fish or critter that fits into their mouths, and fancy goldfish usually grow to about 8inches big while slim ones grow to a foot long or more, so.......
