Does this do what you want:
x <- "Exon start end
5'UTR 22540060 22540121
1 22540122 22540140
2 22540303 22540493
3 22541552 22541565
4 22542373 22542519
5 22544265 22544432
3'UTR 22544433 22544856"
y <- read.table(textConnection(x), quote='', header=TRUE)
# create the plot area
plot(range(y$start, y$end), c(1,7), type='n', xaxt='n', yaxt='n',
ylab='', xlab='')
# create the colored rectangles
rect(y$start, 1, y$end, 2, col=c('red', rep('green', nrow(y)-2), 'red'))
# put labels at midpoints of rectangles
axis(1, at=(y$start + y$end)/2, labels=as.character(y$Exon))
