Switched capacitor IC
Yes you can make switched capacitors on a breadboard, although be aware of parasitics.  What do you mean directly make circuits?  Buy some switches and a cap and connect it to an oscillator.  If you mean an switched-cap filter, the MF10 is well known and available from multiple sources.  Depending on the cap and oscillator you use you could easily get in the 10s of kohm.  The main restriction on the size of capacitor is that it needs to be large enough that it is much larger than the stray capacitance on your breadboard.
