Is it ok to disipline a child and then tell them ...

Of course it is OK to discipline (when I say discipline, I mean scold/reprimand) a child. This is exactly how a child learns what is wrong and right. Once the child understands what he/she has done to be scolded, in a firm voice, tell him/her you want an apology for the behavior and end with an "I love you" and hug and kiss. This re-iterates to the child that although you are scolding him, you do love him and care for him but must be firm about the type of behavior that is and is not acceptable. (This is also the technique that works wonders on the popular and extremely successful television show Super Nanny.)

Yes like mentioned it's OK. I think that the tone of your voice has a serious role in  delivering your message.

Loving discipline is necessary in order for a child to learn boundaries. Even adults receive discipline of some form. Even the Scriptures agree: "True, no discipline seems for the present to be joyous, but grievous; yet afterward to those who have been trained by it it yields peaceable fruit, namely, righteousness". - Hebrews 12:11

after you scold or reprimand your children it's a very good idea to reassure them you love them. Do this after they understand and take responsibility for their actions.
