Can I grow radish on my windowsill?

I'm looking fro something to grow on a windowsill -its a really sunny spot. I'm going to film it on our webcam for the website so I need something that will grow fairly quickly but won't get too big. I've never grown radish befor -will it get too hot inside for it? Help!

 

I think radish would be perfect as they grow rapidly, but not too big. I have grown them in small shallow containers in the greenhouse and they were ok. I guess if the room they are in isn't too hot they should do all right.

 

Yup, one of the best little veggies for growing on a windowsill.

 

Its a pity I cant them grow in the garden!
I think I tried three sowing last year. All failures.
Now... where can I find an empty window ledge?
