The people here won't do your work for you, however most people here will help you learn how to do it yourself. The first thing I'd do in the situation of your class is reformat it, for example in this situation:

        JRadioButton rbDivision = new JRadioButton("Division");
        public justabasic(){
        super("I <3 EraserHead");
        setSize(200,300);

It is very unclear that the constructor started here. If I weren't really looking for it I'd never notice that it's there. You should reformat the class in such a manner that it's very easy to tell how control flow works and where methods are vs where data members are. In fact, how it's formatted, your document looks like 3 separate classes with the first one having no method at all.

The second thing I'd do is look at how a JOptionPane works and start applying that to the ActionListener's ActionPerformed method. That's where you'd want to generate the two JOptionPanes to take in user input and where you'd want to perform the calculation.

Side Note: It's not considered kosher to double-post, especially after less than 2 hours from your original post. Just edit your post with anything additional you want, and be patient. There aren't many people on at this time of night (in the USA), so if it takes some time for a response don't be discouraged.
