85219 Simple Image Creator

Thank you for viewing my project. Basically I want to create a tool for people to create their own online signatures. Here's what I need for this project: 1. User selects thickness level 2. User selects color 3. User creates their signature by holding down their mouse and dragging it to create their signature/image 4. User clicks save and it saves the signature/image that they created. Pretty simple. I retain all rights, and this must be an original creation. You cannot sell this to anybody else. I am open to different programming languages. Please use PMB for any questions.
