Narrative:

We received an initial clearance for a right turn to 020 degree heading; maintain 2;000 until established; cleared for the ILS runway 04 approach at hou. The captain was the PF (pilot flying) and established the aircraft on a 020 heading. At this point; we were fully configured and had an approximate tailwind of 28 knots on the base. The controller asked us to adjust our heading to 010 degrees for the intercept. Upon looking back inside from attempting to acquire the proceeding aircraft; I recognized we had flown through the localizer and asked the captain to come right to intercept the final. The autopilot and autothrottles were disengaged to facilitate a timely course correction. In recognizing the error of no course capture; it was realized the #1 VHF navigation was not tuned to the localizer frequency but the #2 VHF navigation was tuned. As the #1 VHF radio was tuned we descended through the glideslope; the deviation was noted and the PF corrected promptly. The PF established us on the localizer and glideslope promptly and made an uneventful landing. The weather was reporting VMC on the ATIS and we had the field visually on downwind and final; however; due to approaching weather and previous weather at the field we should have briefed an instrument (ILS approach). As the pm (pilot monitoring) I did not verify the #1 VHF navigation set properly for the localizer and failed to catch this until the aircraft flew through the localizer and commanded a right turn to re-intercept the final. Momentarily heads down to tune the ILS frequency and with a fully configured airplane we now allowed the aircraft to descend below the glideslope but trapped our error and adjusted the flight path as needed. The number one takeaway is to ensure both VHF navs are properly set prior to the approach and ensure electronic guidance is always available to the maximum extent possible. The late tuning of the #1 VHF navigation put the crew collectively behind. Although deliberate and positive corrections were being applied and the airport and flight path were VMC; once the error was recognized it would have been more prudent to command a go-around as soon as deviations from prescribed parameters were not satisfied.

Title: B737 flight crew encounters scattered clouds during a visual approach requiring ILS information which had not been tuned in on the Captain's side. An overshoot and descent below glidepath both occur while the ILS is tuned in; resulting in an unstabilized approach.
