Adding 'call to action' or link to slider heading and slider description area

Hi I am building a website using squirrel pro and wanting to add a call to action button where the slider description is. Not sure where I should put the info to do this. The theme options don't seem to allow the use of a plug in so i am guessing that I need to use some CSS on the styling option? I am wanting to be able to put a button to link through to a booking page (the website is for bed and breakfast accommodation). Any help would be appreciated thank you
