NXP's LPC1114 chips (and some others) come with a built-in bootloader. So it's no longer neccessary to upload such a bootloader to factory fresh chips, like it was neccessary with the AVR ATmegas.
Even with a factory fresh chip, you can connect to the chip using a serial terminal (PuTTY, GtkTerm, …).

, 0x3F).OK
.… etc. etc. The protocol is described on p408ff of the LPC1114 User Manual.
If you don't get a response from the chip, press Reset again and start over. If it still doesn't work, it's time to grab the voltage meter or logic analyzer to find out what's going on.
Here's a transscript of the first successful attempt to upload a firmware:
