If found you a little bit of information from portal of European Union (btw. much better than Polish embassy's website)
If you hold a settlement permit, a long-term residence permit or a residence permit and have resided in Poland for at least two years, you are entitled to family reunification.
Your family members include:
your minor unmarried children including adopted children and those of your spouse.
Where to apply? Family members may apply for a residence permit at the embassy or consulate in their country of origin.
You may also submit the reunification request in Poland.
So this describes situation when you have Visa and staying permit (which you will probably have to apply when arriving in Poland). So that means that your wife will have to join you later. Don't know If it's possible to come together.
