chip 16F688,4

#config OSC=INTRC_OSC_NOCLKOUT, MCLRE=OFF, WDT=OFF
dir portc out
start:
for k= 0 to 31
set portc=k
wait 1 sec
next k
goto start

so if you connect your LEDs to the C port (with suitable resistors- do not exceed the maximum current rating) the 4 LEDs should light in sequence from 0000 to 1111 cahnging every second.
