The only way I know of making letters look straight after creating them is to give them a little blur.
The best way to do letters (making sure that antialiasing is checked) so they do not be crooked is do them normally - alpha to select and place a new layer above it, then turn the selection into a path. That doesn't take too long and you can stroke your path too.
Then you are probably better off using the program Inkscape if you want to upscale it. And make a vector ( .svg file) which gimp does not do.
