Hi Vinc,
Congratulations :)
This will solely depends on your favorite activities, do you (and your wife) like to visit places, walk or perhaps seat on the beach in sun.
Honeymoon, usually but not for everyone is pictured as people enjoying sun on the beach, this is the image created by movies, books etc, I gather you want to stay in Poland for that period, if so take a look at reasonable quiet and clean places like Ustka, have been there this year and I can really recommend it, you can relax in this place and eat very nice fish everyday... the only downside I can think of is a number of people you will be seeing every day (this is July, I have been there is September and beaches were still occupied).
If however your honeymoon doesn't need to be in Poland I would recommend places like Maldives, Seychelles islands, Thailand, Bahamas, etc depends strictly on your budget but I believe now you can pick some good deals, if you will have any questions feel free to contact me.
