guys, i have been trying to do this for 4 days straight... i'm not getting anywhere... i really need ur help. i can do the formulas and the action listener and all that, but the only thing that i seem to be having a problem is with the layout of the applet. all i need is a simple window to pop up, that has 2 text boxes for temperatures and a button that converts. i cant get it to be the way i want it to. i've been trying so hard. please help me. this is what i have so far
