The answer depends on how much you really want to spend. I assume that you have a concrete floor at present. You can add radiant heat with coiled
tubing laid on top of the old concrete floor and then a new layer of concrete added. It's expensive and you will loose a few inches (precious for basements). You'll probably need a contractor for this.
A second option would be to add a subfloor with insulation on top of the existing concrete floor. Check your building codes. You may be able to add
solid/rigid insulation (1-2") and a layer of conventional tongue-and-groove subflooring on top of that. The floor will "float" and you may need two layers of subflooring to keep the T-and-G sealed. Alternatively 2x lumber can be used with rolled insulation between. The subflooring can then be covered with tile or carpeting.
