You can grow them from seed, but it is difficult in container. Very difficult to keep it alive long enough to bear flowers. This could take anywhere near ten years. Now let's address the fruiting habits: These trees are dioecious, meaning that there are separate sexes. The male produces the pollen, and the female produces the fruit if it receives pollen. So you will have to have at least two, and hope that one is a female. You wouldn't know for a decade. The more resonable proposition would be to germinate 10 or so seeds. This would be a literal forest that you would have to bring inside for the winter.
The most appropriate action here would be to purchase a dwarf variety that is suited for container from a source that already knows the tree is female. You can then graft a male branch on the tree and it will, then bear fruit.
Long story short... No, one tree indoors will never bear fruit. But they do leech toxins out of the air indoors.
