This should get you close to what you want:
> x <- read.table(textConnection(" X1 X2
+ A 1 2
+ B 3 4
+ C 5 6"), header=TRUE)
> # add rownames to the dataframe
> x$name <- row.names(x)
> require(reshape) # use reshape package
[1] TRUE
> melt(x, id='name')
name variable value
1 A X1 1
2 B X1 3
3 C X1 5
4 A X2 2
5 B X2 4
6 C X2 6
