The topicstarter has an Nvidia card, GUIminer don't work with Nvidia, so he must use Cudaminer.

His videocard is not powerfull, i think 10 Mh/s for SHA-256 or 10 Kh/s for Scrypt mining.
It's a pity to use this for mining.

I think its 10Kh/s

This is a good site where you can calculate your earnings: http://www.coinwarz.com/calculators/bitcoin-mining-calculator

And this is also a very informative site: http://mining.thegenesisblock.com/

Nvidia is not really good for mining, you can compare on this site how much Mh/s you will get: https://litecoin.info/Mining_Hardware_Comparison
And with an Nvidia card you must use Cudaminer: https://bitcointalk.org/index.php?topic=167229.0
But honestly ... with this kind of hardware you will lose money.

Maybe if you really wanna mine, you can buy an ASIC miner, an USB antminer is only 1600Mh/s but is cheap and is 50x more powerfull than your setup.

What is your mining hardware?
If you will be mining with VGA cards, it will be better to stick with altcoins, but if you really wanna mine bitcoins, you can try http://middlecoin.com/
