I did exactly same thing - spilled a glass of red wine on my HP laptop. I ended up ordering a new keyboard on ebay and put it in. Couple of things: Win7 has an on-screen keyboard that you can use to log in and do minor configurations and you can also buy an external keyboard, maybe Bluetooth, and be done.
If you have too much valuable software on the laptop you can buy an identical used machine and just swap the hard drive. Replacing kb is usually much more work than swapping hdd.
