package BarCharts first, then you can customize BarChart3D with the
option Ticks that accepts a list of lists of lists of the form {{{pos
1st x-tick, "value"},{pos 2nd x-tick, "value"},...},{{pos 1st y-tick,
"value},...}}

Needs["BarCharts`"]
heights = {{1, 6, 8}, {2, 7, 1}, {3, 1, 4}};
BarChart3D[heights,
Ticks -> {{{1, "1990"}, {2, "2000"}, {3, "2010"}},
{{1, "A"}, {2, "B"}, {3, "C"}}},
TicksStyle -> Directive[Orange, 12]]
