Others have mentioned that it's difficult, but I think it's worth mentioning that they haven't really started to explain why it's difficult.
First, you have to make an appropriate unregulated voltage source. This is something like a simple step down transformer with an associated diode bridge (aka bridge rectifier). This gives you a DC source from an AC source at a specific voltage, but it does nothing to ensure that voltage supply stays constant when you try to connect things.
Regulating the voltage supply is possible, but you need to understand voltage regulators, and voltage dividers, to ensure your voltage regulator does it's job.
After that, you need to know what sort of battery you have (lithium polymer versus something else) because it changes exactly how the battery needs the charge applied to it.

Now... if you're asking if you can just throw that cellphone on usb port on your computer, most cellphones do have a circuit that recognizes a computer input. if this is the case you might be able to simple hook the phone up to a usb port on your computer and charge it, without a whole lot of fuss.

To even start to think about how to answer, we would need the model phone, and the batter type ( Samsung Landline batteries ) and then, without knowing the "charge rate" of the charger, we still would have almost no way of giving useful advice.
