The difference between: Me gustaria que venga / viniera?
Viniera o venga?

Me gustaría que venga-- I would like it if you/he come.
(Me gustaría si viniera) // possibly ''Me hubiera gustado si viniera'' would be better -- I would have liked it if you/ he came.
That's the best I can do. One is present subjunctive and the other past subjunctive.
The present would still be "Me gustaría si viniera." When using the conditional, that "if-then" form is always used, with that subjunctive form, regardless of tense. However, if you're using the subjunctive for the other uses, it would depend on the tenses, which should match.
