answer: Yes, Judaism teaches that righteous people outside of Judaism can reach G-d and heaven. That's why they don't try and convert everyone and conversion isn't an easy process. You don't need to be Jewish to reach G-d.
That said, if you want Jewish answers, you REALLY need to post this Saturday. It's Yom Kippur, a high holy day in Judaism and Friday is the sabbath, many of our Jewish friends are off line.
