Being sure means nothing unless you have some data to support your
conviction.

This doesn't even follow from the above. I have no access at present to
Hamp's brief article on <gjuhë> in _Studia Linguistica et Orientalia
Memoriae Haim Blanc Dedicata_ (Wexler et al. [eds.], 1989), where his
etymology is laid out, and the last time I saw it was some years ago.
However, Hamp analyses the dialectal forms of the word, not only the
well-known ones such as /gluhë/, but also /gûh/ with a nasal vowel (in
some varieties of Geg). His evidence suggests Proto-Albanian *-unh-, so
he proposes *dlunhë, which he sometimes connects with PIE *d(l)n.g^Huh2
'tongue', though I can't remember the details. Anyway, whether Hamp is
right or wrong, the dialectally preserved nasal vowel means that your
derivation is incorrect (whatever its other deficiencies).
