Can a single technology be used to observe light at any wavelength? Radio waves are observed using induction in antenna.
Visible light is observed exploiting electronic transition in matter.
Is it possible to do the opposite?
If not why?
 A: Yes. Potentially black body absorption can convert all radiation into heat, which can then be detected.
A: It is common sense to mix phenomenons electromagnetic radiation and radio waves. EM radiation is the result of electron acceleration. Then higher the acceleration then higher the photon's frequency. Different from this the frequency of radio waves is the modulation of electron acceleration made from the antenna generator. But at the end antenna emit photons too. So what you want to detect really are photons, in a chaotic way from any EM radiation or in modulated way from an antenna. And any photons one can detect with a bolometer.
The real add-on of radio waves is the fact that with the help of the modulation one can receive and separate informations from the all around existing EM radiation. The energy of radio waves in the point of the receiver can be tiny comparing to the EM radiation all around. That is the point why you need radio receivers for radio waves and you will be not happy with the bolometer.
A: I don't know that much about this technology, but the nantenna is a tiny antenna that in principle can detect visible light; however, current implementations are still restricted to the infrared spectrum. While nanotechnology lets you scale antennas down to the nanometer range so that you can detect visible light and even ultraviolet light, I don't see any way that the technology could scale down to atomic and subatomic length scales, so you can't use this approach to detect x-rays and $\gamma$-rays
