Hey Michael,
I'm fairly new to this too and I recently dealt with this problem for my first time as well, sort of, I had 2 windows. What type of light are you looking for? What time of day?
In the case you're looking for very directional morning light (in my case, I was) I may be able to help you. We had a very limited budget and could only afford 2k fresnels, so I opened the barn doors all the way up, set it to full flood and placed it outside about 5ft from the window. We were shooting digital and I was able to get a fairly decent exposure, depending on the stock and how fast your lens is it may work for you too.
I too thought it wouldnt work but it actually did and gave us some pretty believable sunlight.
Here is what I got:
