    Welding magnets, corner clamps, clamping to a table, tack everything in place the do the full welds.

    Measure opposing corners after tack welding and make sure they're equal, if they aren't equal they aren't square

    Then there is welding sequence as well, weld corners first etc. Spread heat around. Keep gaps to a minimum.

    Also worth mentioning that you can be square in the XY plane (ie both corner to corner measurements are equal), but warped in the Z.
    An easy trick is to run two string lines across opposing corners, and check that string touches where they meet in the middle- if they do it's flat. Working on a flat surface really helps, but not everyone has that luxury.
    Do this measurement after tacking, and keep heat control under check while doing the final weld out.

    We use turnbuckles to help hold things square, also putting diagonal braces helps hold things where they should be.
    As others have mentioned, stagger the welding sequence, and don't put too much heat in the one corner.
    To grow old is mandatory, growing up is optional.

    If you haven't got a flat surface to start with, you can fake one with a couple of straight bits of steel (or even timber). Use a spirit level and shims etc to get them level first, then work off them.
