  We study a GUT-inspired supersymmetric model with non-universal gaugino
masses that can explain the observed muon g-2 anomaly while simultaneously
accommodating an enhancement or suppression in the h \rightarrow\gamma\gamma
decay channel. In order to accommodate these observations and m_h \simeq
125-126 GeV, the model requires a spectrum consisting of relatively light
sleptons whereas the colored sparticles are heavy. The predicted stau mass
range corresponding to R_{\gamma \gamma}\ge 1.1 is 100 {\rm \ GeV} \lesssim
m_{\tilde{\tau}} \lesssim 200 {\rm \ GeV}. The constraint on the slepton
masses, particularly on the smuons, arising from considerations of muon g-2 is
somewhat milder. The slepton masses in this case are predicted to lie in the
few hundred GeV range. The colored sparticles turn out to be considerably
heavier with m_{\tilde{g}} \gtrsim 4.5 {\rm \ TeV} and m_{\tilde{t}_1} \gtrsim
3.5 {\rm \ TeV}, which makes it challenging for these to be observed at the 14
TeV LHC.
