Learning Spanish is difficult, especially for someone who might have little exposure to it. I took 3 years of high school Spanish, a summer immersion course, and was the only white guy on a maintenance crew in college.
Intro Spanish won't get you far unless you plan on talking to your father in law about numbers and the color of his pants. That said, you can learn. Spanish is much more efficient than English because it has rules that are consistently followed.
Verbs have six tenses: I, you (formal), you (informal), he/she/it (singular), we, and he/she/it (plural; the equivalent of "them" or "those folks"). There is another form in Spain Spanish which you don't have to worry about. Because Spanish is a latin derivative, it also is highly gendered. Everything has a gender. Masculine things are identified by "el" and feminine things "la", and end in "o" (for masculine items) and "a" for feminine items. There are some exceptions to the el/la rules, but these are few and far between.
The big thing is learning the alphabet, present tenses, and then a bunch of verbs and adjectives. Someone suggested Rosetta Stone. I've never used it, but it is highly rated. You can probably get some used books online too.
Good on you for making the effort.
And a succinct beginner sentence is "Hola, (yo) soy :your name:." Hola is hello. "Yo soy" means "I am", and soy implies the use of yo (this is how Spanish is efficient. Tenses imply certain verb forms, and subject verb agreements follow this pattern). Like I said, there are exceptions, but the patterning of the language helps beginners.
Best of luck to you.
