The rectangular selection tool may be what you want. You can add and subtract from an existing selection using the shift, ctl, and alt keys to build up fairly complex selections with sides that are all either horizontal or vertical.
Another possibility is to use gfig to select arbitrary polygons. But you only asked for horizontal and vertical.
