If you build a prototype on a breadboard, and something comes loose, it will be stuck under the glue, and you won't be able to fix it very easily. And the glue seeps into the holes, and actually makes the connection less reliable. If you want to have some wires semi-permanently attached to a breadboard, then just use regular "scotch" tape, as it is easily removed, and does not leave sticky residue.
If you want a more permanent circuit, learn to solder.
