WebSynthesis of GBL from THF WebWith NaNO2 it will produce GBL, which can be hydrolyzed to Na GBH using NaOH or NaHCO3. For 1,4-butanediol you'll need a completely different synthesis pathway, the only realistic way would be from tetrahydrofurane. It should be possible to hydrolyze it to 1,4-butanediol by boiling it in dilute sulfuric acid.
